Slight wobble under braking

[jimbo]

Having got just about everything else sorted on suspension and steering:

 

TCAs

Tie rods

Bushes

Bearings

Tyres

Wheel balance

Tracking

Discs

Pads

 

I still have a slight wheel wobble when braking (though the car doesn't pull to either side)

 

The only thing I can think that I might need to look at is fitting new spring clips to the pads, but is there anything else I should consider. All suggestions greatly appreciated.

 

Cheers,

Jim

Could it be a stuck piston in your brake caliper?

had that on mine after new disc's pads etc.

and it was a sticking caliper

[jimbo]

Is that sticking as in sticking in (not applying the brakes properly)?

My bro had that and it was a combination of steering rack bolts working loose and rack rubbers gone.

one caliper was not comeing out quite all the way and slower than the other one, but a quick clean up soon sorted it

Rubbers as in the mounts, not the gaiters, I figure

 

I'll get out tomorrow and check for rack movement whilst the missues turns the wheel.

 

If it aint that, I'll be ordering a service kit for the calipers.

did you check the hub for trueness... it could be distorted and that would be the result brake wobble...

more like a warped disk

Cheers for all the input folks. With your help, I'm sure to get this cracked.

I replaced them 6 months ago (just because they were nearly gone) and when I fitted em cleaned up some burrs on the hub/disc mating face. The dial gauge showed them to be within tolerance before the wheels went back on.

How do I check that?

 

 

OK. Well I got the missus to turn the wheels whilst I laid under the car. The rack moves about 2mm in its brackets, through one lock to the other. Could that be the answer, or would I be looking for more play to cause the issue I have.

[abarth78]

you check it with the dial gauge as you did so thats sorted....

 

if you have some play in the steerins system... that might cause trouble...

I hope then that some new bits of bit rubber and tightening the nuts should do the job. Watch this space.

 

Cheers,

Jim
