Title: Brake pull the 2nd
Post by: frostbite on 11 April 2017, 15:44:46
I have just had the wishbones and the tracking done,
Now the brakes are still pulling to the right, I have been under the car and greased the sliding pins which had the sticky black stuff on, Now I'm left with sticking pistons, both front discs are shiney even after being off the road for 4 months

The problem I have is, if I stomp the brake with no hands on the wheel while moving on tick over the wheel will sharply twitch to the right, If I did it enough I think it would turn in the road.

Could the NSF caliper be the culprit?


cheers

Define tracking ::)

In simple terms, did it cost less than £50, or more than £80?

I had it on a hunter, after the gimps that set the lower arms couldn't laser track it for some reason IDK

Didn't answer the question...

Also does it drift the same way hands off on a level Road?

It drives straight if no brakes are applied

the toe was way out, it was squealing and tramlining after the wishbones swapped

What about camber and castor?

I have a print out to show, its not the best

I have found another fault, the wheel wont return when I turn right it will lock itself, the wheel returns if I go left

Front left camber is WAY too much. The back on that side isn't good either. What you have is a typical That's close enough alignment by someone who doesn't realise/care that Omegas are particularly sensitive.


Take it back and complain. If they're incapable of adjusting the front, demand your money back and go somewhere competent. Camber is easy to set, and is critical to how the car drives.

Is that the reason for the wheel not returning?

That's horrible,  as said go back for a refund and find a garage that can ACTUALLY do the job instructed of them :o

Oh dear, oh dear, oh dear. Just because they have the machinery doesn't mean they know what to do with it. A quick search should show up the right settings, remembering that work softened front springs need to have the camber more vertical to stop accelerated front inner edge tyre wear.

None his should result in a pull under braking though...

It would hint at the NSF front calliper or associated hydraulics so its worth a quick bleed through, checking again the callipers are free to slide and, with the bleed nipple open then closed, work the piston in/out to ensure its free.

Other item that can cause a pull under braking is wishbone bushes or a poorly tightened wishbone bolt.

No, agreed, but the left side camber being so far out is going to change turning characteristics, add to it the toe on the right rear and I'd have thought it would be a bit all over the place even under normal driving. What does worry me a little is the excessive camber on the left rear relative to an OK toe in.

The arse end is a compromise, but should be pretty balanced side to side.

That they have set the car up without a zero thrust angle suggests lazy/incompetent operator. If they couldn't set it due to seized/bent rear track rods then they should have said so..

I suspect one of the track rods is bent, probably from being forced without enough heat/preparation.

see what happens once you have had it re set up .then as well as front brakes check rear calipers too. this can also cause a seeming like pull to one side .if you have any small hose clamps worth locking off rear brakes and driving on a non public road to check if its the fronts causing this or vise versa to see if its the rear. then at least you know which end your looking at.

then once youve found out if its front or rear brakes causing the pull you need to find out if its the brakes themselves or a brake/suspension related pull.if its front .have someone stand at the side whilst you apply the brake.the wheel should not jolt backwards whilst doing this or it would indicate movement compared to the other side .your then looking at softer wishbone bushes on one side ,bolts not tight,lower balljoint or tre movement.
