Follow up on post 51090 When I slam the brakes hard

I don't have ABS and there's no oil marks or anything that looks out of place. When you brake the car will move to the right depending on how fast you go it could be 1.5m's that it moves and very scary at high speeds. By sometimes I mean it will do it and sometimes it won't....very strange

Could be piston stucking. Have you tried thoughtfully flush your system? Also you can take pistons off and inspect internals for any strange marks or rust or something.

Troll Harrow is spot on...this is sometime the 'last resort' for brake balance problems.

If you wish to diagnose beofre you spend the money on new hoses...try swapping them over and see if the pulling swaps to the left side.

Just remember your suspect brake is the left side that isnt performing as well as it should.

Have you had the wheels of and pushed the pistons back a little and also ensured the caliper slide work well?

Im not sure what you have done in the past but this is what I would do...

Flush the entire system....bleed the master cyl till it sucks air then refill with a new fluid that has different colour. Bleed all four wheels till the new fluid comes through.

Then with the wheels off you should be able to push the pistons back a little by hand and that will also now allow you to move the floating caliper back and forth a little to prove they are not siezed or grabby.

Then wheels on...pump pedal a few times and test drive....if no better swap the lines over from left to right bleed and retest drive.

If thats not sorted...park in Balga with keys in ignition!!

All the best

He says "sometimes". I reckon that in case of house it would be consistent behaviour. Still worth to try.

Hey Matt

They did check the pistons at the shop this morning and said they moved as expected. I will take it to another brake place during the week and see what they say

thanks

I fell for the old 'internally chaffed brake hose' trick in my 50's Dodge. Replaced / recond everything except the front hoses. Couldn't work out why it would pull to the left all the time. Someone suggested change hoses. I did this, stipped & cleaned front wheel cylinders and hey presto, no more crazy breaking. Also had a problem on my old GQ Patrol. Turned out that right hand outer (I think) pad was severely glazed over. I took the pads out and gave them a rub on some course sand paper and it fixed it. Troll, did they change your brake pads?

They didn't do the pads but I did them about 2 months ago and he said the pad wear is even so the problem is not there

Errrr… Its getting really funny. If car pulling to side, than it is obvious that it brakes more by one side then by other – no other forced around (except of God or Devil of course). Thus eventually pads have to be worn differently. Unless it happens once in blue moon.

No sorry Serg you are wrong.

Brake faults in 99% of the time DO NOT BRAKE BETTER....THEY BRAKE WORSE so the the vehicle will pull to the side with the GOOD brakes and away from the side with the POOR brakes.

Leaking wheel cylinder...reduces brake efficiency at that wheel
siezed piston....reduces brake efficiency at that wheel
siezed caliper slide...reduces brake efficiency at that wheel
damaged brake hose (blockage)...reduces brake efficiency at that wheel

need to go on mate?

Matt,
Agree with everything what you said. It seems to me that you miss my point a bit. I have said that if it pull to side, then it is obvious that one side brakes harder then another one (for any of those listed and unlisted by you reasons or combination of them). But if problem consistent, that with time there should be uneven wearing on opposite pads.
