hey ppl... been playing around with me breaks. Replaced my brake booster with a V8 one. The booster and master cylinder have been checked and are working perfectly. After bleeding all the brakes and testing them i found that the back right wheel will only lock under full braking... the rest wont. From factory (brand new brakes) which should lock? the front or back? i thought it would be the front... but i cant get them to lock. Standard disks on the front and standard drums on the back.
cheers

I actually had this same thing on my torry. The rear right wheel would ALWAYS lock first.
I did manage to get all 4 locked up on a concrete road... hehe looked awesome.. 4 wheel slide toward the gutter and stopped directly in front of my mate who i was picking up... LOL couldnt have done it better if i tried!!
Dont know why.. just seemed to happen, i never worried about it!

The engineers of this world tell us it's ideal for the front brakes to lock just before the rears. This is to help us incompetant drivers to stop the car in a straight line. Ideally, you should never lock the brakes if you want to pull up in a hurry. If your rear brakes are adjusted correctly, I can think of three possible reasons one side locks before the other.
#1 Dirty rear linings
#2 Glased rear drums ( bit of emery tape will fix that )
#3 One tyre grips better than the other.

the main reason the back left doesnt lock would probably be that the shoes got drenched in brake fluid because of a piston fault. The car stops in a perfectly straight line. Theres a big black mark for 15 metres outside my house to prove it LOLLL!! Are the front supposed to lock up? does any1 here have stock brakes all round and the front discs lock?

Then soak them in metho to get the fluid out. I mean, what's the worst thing that could happen if the car doesn't stop in time?

Drum brakes will always overpower disk brakes. It's bit of a problem with the Torries, particularly on a race track. Forget any notion of trail braking in the Torries, unless your masterful on the brake pedal (i.e. paying attention).
How hard are you braking? One way to ease the problem to stop the drums biting on is to grind a 45 degree bevel on the leading edge of the brake shoes.
I have HQ ventilated front disks, which seems to even it out a bit, but not much. I imagine the standard set-up would be a bit worse (i.e. not ventilated disks).

Mine does exactly the same thing, and it really annoys me. I haven't made a bevel but I plan to. It doesn't bother me so much in the dry but the wet is another storey as the car wants to spin around on me and it is not fun to stop sideways in an emergency situation surely there is a fix.

The cheaper way out would be to install a better quality pad in the front. What calipers do you have? The more expensive option is to install an adjustable proportioning valve in the rear brake circuitry.
