Brake Issues WOF

[1994legacyrs]

Well my 1.6l 1993 impreza failed on a few things for the WOF but I need help on the brake related issues. I haven't really had much to do with brakes other than bleeding them etc so I really don't have much idea on how to adjust them and what-not. I might just have to take it into a mechanic and bite the bullet but I thought it was worth posting here first.

The first issue is that the rear brakes are quite imbalanced - the left coming up as 112 kN and the right as 167 kN. Under heavy braking I often feel a shudder which might be because of this. Is there any tricks or checklist to go through when dealing with this sort of thing?

The second issue is that the front right brake has "seized". I don't think it has actually seized but it doesn't freely turn (spin the wheel and it will just stop). Could possibly be a wheel bearing but I am sure the WOF inspector would have picked up on that.

Any help would be much appreciated,

Cheers

Drum or disc rear brakes??

The front is probably a seized caliper.

Drums on the rear,

The weird thing is that the front right brake works fine - its even slightly better than than the left one. I thought if it had seized it might effect its braking ability?

Pull the drums off and see if a wheel cylinder is leaking.

Nah it's usually a seized caliper slide pin, not a seized piston. The inner pad will be worn if it has a seized slide.

Checked both drums and nothing out of the ordinary or leaks around the cylinder. A lot of dust and crap so I cleaned them both out.

The front brake didn't show any premature wearing or seizing either, put it back on and bolted everything up and it seems to turn a bit easier for some reason but still has quite a bit of resitance.

I am stumped ???

Crack the bleeder off and see if you get a burst of brake fluid. Could be a faulty brake hose or master cylinder.

if the rear still has an imbalance, split the shoes, take one off each side and swap them over, also swap the drums from side to side, use emery tape to clean the drum and shoes up, adjust them up and ride the handbrake all the way to the testing station.
