Hi Ben

do you have any photos of your rear brake setup, I'm looking for hints and clues in relation to the nine inch with hand brake shoes, as I have the same calipers as you.

Cheers.

In that photo they are 28 x 9.5" on 15 inch rim, it's been tubbed and there was bugger all clearance all round at that ride height, could run them if i jacked the back up an inch or so or could easily run with 26" diameter slick. Fitted up some 10" wide rims a month or so ago with with 3.5BS and 295/50/15 s had to take off the weel studs to get it in there. Had 1mm cleance on the outside but 1" on the inside. I could run them if i could find a 4" BS rim that i liked but i rekon that would be impossible. CBF getting the diff cut down to suit so guess I will have to settle for 8in wide rims :-( 10" rims looked the part though.....

Here you go LX8vd77. Standard VR/VS backing plate, handbrake, disc and calliper. Haven't pulled the axles out of this diff yet so not sure what bearing/seal set up it uses. Have read there is issues with axel slop but mine are ok.

And complete VR setup on my VR ute for reference (notice that the handbrake pads have actually just fallen off the backing plates)
Posted Image

Brought all of the bits to upgrade when i swap the fronts over to AP 4 pot callipers and aluminium hat 5000 series discs. If u wanna upgrade the back VR/VS setup use VR/VS backing plate and handbrake setup, VN calais vented rotors - same handbrake set up so you just have to change the disc and calliper (needs new caliper adapter bracket). I plan to use R32 2 pots with thoes VN discs. I think i posted some photo of these trial fitted on the previous page or in the brakes section.

Have ordered a 20 mni fuse Ez wiring kit, electrical crimp set, satelite tracking and alarm system so might have a crack at rewiring this weekend if i don't have to work.

Fell off the radar for a fair while, so time for an update.
Ends up I ripped my ACL off the bone so was out of action for a few months but all good now. Worked away for the best part of 5 months so have basically done nothing to the LC this year.
Started on the wiring this week, Did a bit of investigation to find out why I almost had a massive electrical fire. Found countless bare wires, but the main culprit was when the previous owner had installed the GTR dash he pinched the main power wire, which must have wore through and created a short. There was heaps of smoke pissing out from under the dash so this was definitely the culprit as these wires had the most scorch marks.
Tried to follow the previous loom to see where everything ran but the loom had been so butchered I gave up and decided to just rip it all out and start from scratch.
What a nightmare......

Used an Ez Wiring 20 mini blade fuse kit costs 350 delivered from air ride and suspension. Fuse box is nice and compact and well labelled. You can also switch which side the wires come out of for easier mounting. Wires are colour coded and labelled every 200mm or so. Main wire from the starter is 10 gauge and wires get smaller depending on application.

Posted Image

Posted Image

Kit also includes 2 x headlight multi connect plugs, pre-terminated high beam multi-connect, dash light switch multi-connect that all fit the OEM Torana gear which saves some time.

Posted Image

Posted Image

Posted Image

You have to remove the wires from the pre-terminated column/ignition multi-connect and plug individual wires straight in or just insert them into the original loom plug.

Posted Image

All in all a pretty damn good kit and at a 1/3 of the cost of the painless kits it’s fro%king brilliant. However the instructions are a bit lacking and you will definitely need a colour copy of the original wiring diagram for reference.



Anyway loosely split all the wires into batches and plugged everything in. Attached the positive terminal and held a test light across the negative terminal to the negative lead. Light on = short. Since it was the first time I had rewired a car, I assumed I had stuffed up and removed the fuses one by one to find the fault. Fault in the accessories, checked all, all good, so was a bit stumped. Ended up checking everything again, eventually worked out the short was coming from the alternator exciter wire. Ie power was going to the alternator through the normal power wire and must have been fried internally and was shorting and coming back through the alt exciter wire giving the accessories power even when the ignition was off. Just unplugged the exciter wire for now, will have to buy another alternator later.
Tried to start the motor, but no joy. Turned over ok with starter, checked that fuel was ok, had power at the coil.
Tested the ignition switch, all worked except had power to the positive side of the coil in start position only, but not in run. Will rebuild the switch at a later date so as a temporary measure just bridged/piggy backed the two wires for the +ve side of the coil onto both terminals on the switch. Problem solved……. not. Went to start it again and still didn’t start. Pulled the dizzy cap off and no spark when cranking, reassembled and removed a spark plug lead and no spark when cranking. Figured it had to be the coil so stole one off one of the parts bomb cars in the back yard and hooked it up. The starter also has a small short in it internally somewhere but only when it is in the start position so will just use it until it dies. Cranked it over again and fired on the first crank, so cracked another beer to celebrate. I assume the damage to the ignition switch, coil, alternator and starter were all as a result of the short that almost started the electrical fire.
Next step is to work out where I want to run the wires and tidy the loom right up. Still need to hook in the lights and a few extra accessories and test. Also have power windows, keyless entry, security system and stereo to install which I’m assuming will be a PITA.

Good to see you're slowly getting back into it.If I had choice I'd go with an ls1 6spd...or chev as 2nd option.
Did use old toyota handbrake,shortened vs ute cables & new tunnel to clear 3" tailshaft(headache lol).

Car is nice..are wheel are stretched or standard & did you move diff back/forward at all?

Hey GTR boy, trans tunnel was modified for the T400, standard tunnel, LC Handbrake lever, VR handbrake cable shortened with new threaded ends swaged onto the front of cable (to allow it to bolt upto LC h/b lever) Haven't made up permanent brackets to attach it to the floor pan near the back of the tailshaft, but temporarily used a couple of rubber coated fuel line clamps and screwed it to the outside of the factory torana retaining points and works ok.

Put the front and rear brakes back on and took it for a quick spin but was braking down at high revs. Lent the timing light to someone so tried to adjust the dizzy advance by ear without sucess. I also suspect that the twin point ignition is out of wack, but its good enough to move the car around while working on it.

Since i've been away so much everything is unregistered/un road worthy/broken/messy/lost so decided to knock off a few jobs. Brought a second hand passangers side axel from the wreckers as the one on the VR Ute daily driver was mega bent however the TA at the wrecking yard removed the drivers side axle, which is too long. Had to go back and swap it again. All went in nice and easy and had the diff jacked up on that side so didn't have to change the oil. Fixed the exhaust bracket, replaced a tail light and found exposed wires in the inner panels so tidied that up, some new bulbs, replaced the pedal rubbers. Battery had leaked at some point in the past and eaten through the body work, previous owner had repaired it but had rusted out again so repaired that. Wires to the starter relay had corroded out so rewired that. Hadn't washed the car for over a year so it was brown/black instead of white and mold had started getting into the paint. Had to wash it 4 times to get it back to white but cleaned up alright. will need a good cut and polish but have better thing to do for the short term. Took it in for rego and had to wait about 4 hours - Darwin MVR is a joke, had one poor bloke trying to cover 2-3 inspection bays simultaneously by himself while 30-40 cars waiting. Passed even though the ute is too low and bottomed out during the check.

Cleaned out the shed and garage also yesterday so i could actually find and use stuff. Today my dad came around and helped me put up the A-frame/engine hoist. Stripped out the slotted rotors, brakes, diff, motor, box, new rad, ac, fuse box, nudge bar, towbar and seat rails out of a parts VR Ute that i brought a while ago for 300 bucks registered but guy had wacked a tree with the drivers door so the door could not open. Could have easily fixed it with a new door and sill but just going to keep the parts for other projects and sell the body for scrap as need room for the new shed which is well overdue.

haha good stuff! She doesn't have a name yet, so might have to call her "Brown Note" or "Durty Nelly" (after the irish pub) ie driver says to unsuspecting passenger "Have you ever herd a brown note?", reply "no", then you just floor it on a launch.....and then......
As long as the passenger doesn't crank out a number 3, as you would probably have to burn the car to get the smell out after that.

Looked up the cast code 3858471 for my engine today it's a July 1964 327CI block from a chevelle, Camaroor corvette and most likely has 2 bolt mains. Couldn't find exact tuning specs for that block but the 327 specs were generally 31-34 deg Dwell and anywhere 8 deg BTDC to 2 ATDC. Timing light said i had 35 deg dwell and timiming was way out so i just set it to 4 deg BTDC. Runs and starts alot better than before.

Was still braking down a bit in the top end when i took it for a drive. It seems as though the TH400 is slipping like a bitch, I thought it might be low on oil but added some and didn't improve. I'm not an auto guy so what do you guys think it is likely to be?

Ordered 2 of these hairdryers to install under the dash as demisters, not sure what I will use for heat resistant ducting yet.

Finished off the seat frames and rails for the bucket seats and installed today. Just have to replace a couple of the bolts with 8.8 grade socket head cap screws, then one more job to cross off the list.

JB Hifi had 30% off this weekend and Alpine is running out their old models so got double discount. Big savings for example the top of the range single din head unit RRP700, paid 270ish, so ended up buying a full system for the LC.

what are thos brake boosters in the boot? Just curious if they are the same that i ordered.

I saw the your post on my thread about the diff possibly hitting on the floor, did you mod yours? If so how much was need to clear it enough.

They have a PBR casting on them but dattoman said they were PBR hydro powers and the casting number didn't tell you anything. I would have to strip them to determine the bore size and diaphragm size. Below is the reference chart
Posted Image

For reference what sizes and/or p/ns are you buying?

With my setup the pedal is spongey with excessive travel, so will have to rebuild mine, might also just delete the boosters altogether and install a pedalbox with balance bar.

Tere is more info in my brake thread
http://www.gmh-toran...4pot-callipers/

As for the boot floor i haven't modded mine yet as I don't know my finished ride height with new rims and tyres, but i rekon there is a 30% chance the diff centre will bottem out. My brake hoses might rub also at full travel.

Ok guess I might chop into diff tunnel and partially into tail shaft tunnel. The brake boosters I'm not sure what the brake place has ordered me, all he said was vh40 and vh44 I don't know which will do front and back. He just told me to mount them and he'll do the rest. Mine should finally be here this Friday, apparently the supplier in Sydney forgot about me until I chased it up 6 weeks later. Lol
If at anytime you want to swap torri's let me know. :)

The VH40 is bigger and will be for the fronts.

I wish i was in your shoes and i could build the car the way i wanted to instead of fix/rebuilding everything that was ment to be fixed/finished by the previous owner.

Might do a few tests to see why my brakes are spongey I suspect it might be the XA master as it is not really ment to be a disc disc master.
Test 1: pump pedal a few times then hold the pedal in firm. Start engine and see if the brake pedal drops a bit, pedal effort should decrease also if the boosters are working.
Test 2: Remove vac hose before it splits and goes into the boosters and attach vac gauge. will hopefully be >16 inches of vac.
Test 3: Measure pressure entering each booster.
Test 4: Measure pressure exiting each booster.

Got my parts from rare spares, polished windscreen washer bottle doesnt have an electric pump supplied which is pretty useless considering how much it cost. Also recieved my hair dryers they are nice and compact + lite. Attempted to remove the folding handle but it has special safety screws that i have not seen before.

Hey ls1lj,

Great build and read mate, very very simular to what I want to build (when I find the right LC), which also mekes it very educational for me.

I'm in Darwin too so I feel your pain trying to get things done up here.

Keep at it brus, hope to see it out and about around Darwin soon.

Cheers Bullet
