Outer Limits 4x4 Board

my runner has started pulling to the right under brake. not sure why. does asnyone have any insight into the possible cause. cheers

Always go back to basics. For some reason youre right front brake is pulling up more efficiently than the left. Take the wheels off and have a bit of a look.

i just changed the whole axle and hub setup on the left side and the disc had a bit of surface rust on it. could this cause it to not grip as much on that side?

How severe is the pull? Did you get any fluid on the discs?

had a steering alignment done lately?

Does the disc still have rust on it now that it's been driven? Does the pedal feel any more spongy than it did before? Do whe wheel bearings have the correct preload applied?

i'd think either a brake disc/pad/caliper issue (air in the lines even?) on the left side, or a dud wheel bearing on the right side.

Pulling to the right, rust on the left disk, siezed left caliper is my guess.

My Sierra did this.

It was a leaking axle seal, leaked oil all over the disc.

You have been working on the left side, maybe you damaged the seal... this would cause it to pull to the right.

no need to guess.....

seized left caliper IS the problem

cheers for the ideas fellas. i know the left caliper works cause iv tested it. there are no leaks or anything. didn't touch brake line so i no that i haven't lost pressure in it. so thats not the problem. probably just need to wear down the surface rust on the disc and should b fine. ill drive it for a week and see how it goes. if the problem persists then ill look into it more. but thanks for all the ideas guys. cheers

The build up of scale on the disc is evidence that the caliper is either not working or is not working well enough to make contact with the disc. It may have been working under test, but not when you need to stop. I've had pistons sieze due to mud ingress, could this be the case?

It's obviously bad enough to put a post up here,

Don't drive it untill you've fixed it. If you have to brake in an emergency and end up heading towards oncoming traffic...............

Rust on the rotor shouldn't make it pull right, the rust would have been removed after the first few applications.

My money is on a seized pistion on the LHS caliper. I know you say you've tested it, but if it's full of mud and scale it will stick now and then until it gives up and seizes for good...

Take it to a brake joint and let them have a look.

sorry to clear up. the caliper is the one iv had on my car since i bought it so i know that its working. there is no problem with the caliper. iv taken it for more of a drive and it seems to b fixing itself. so ill keep u posted. cheers

I used to change lanes by touching the break pedal
it was the wheel bearing wasent farked just badly lose

Get your alignment looked at, if replacing all those parts altered your castor or camber it could cause it to pull under brakes.

Have you noticed any steering differences as well?

yeh little bit more pull to the left wen driving in a straight line. only very minor though. might get an allignment done and c if that helps. cheers struth. hey i havnt got that part yet. did u send it on monday?

went for another drive today. the slippery surface rust has all been worn down and my braking is now back to normal. thought that would b the problem. cheers for all the help guys
