Front caliper/s sticking/not releasing properly causing the rotor to overheat and warp as speed increases?

I remember with my BMW if I didn’t give the surface rust a bit of a clean up on the mating face of the brake rotor, I used to get a wobble up around 80kph.

It’s got brand new wheels and tyres mate....

Wouldn’t there be a pulsating problem through the peddle there isn’t Dave??

Ain’t that the frOcking truth

Had a mate with new tyres drop into myself one day with the same problem. We took it for a drive and it worked out to be a defective tyre. I would check the balance weights have not fallen off. I would also check the bearing for over or under tightening. But a wheel rotation is were I would start.

Rotors..meaning the bolt up part as opposed to the bit the pads run on?

Hmm...have you also tried running 50psi and then 20psi in the tyres just to see what that does?..i.e maybe push you towards dodgey tires..but youd want to be unlucky to have it with different sets.

Assuming front wheel drive...have you tried it on a dyno...just to 100% isolate it to the issue being the front?

Disc brake rotors are the part the pads run on, with or without an integral hub or a hat design to fit onto a wheel hub/axle.

I expect you would get some feedback through the pedal if you lightly rest your foot against it and the shimmy would be aggressive if you applied the brakes.

Have you tried lightly applying the brakes while the steering wheel is wobbling?

 

If not the brakes causing it I would definitely consider a faulty tyre.

Actually both. When I replaced the rotors, I had to sand the hub that it mounted to as it has surface rust on it. Hen every time I took the wheel off I had to give the mating face of the rotor a clean up. Seemed minor but it would always wobble if I didn’t do that.

After all the new gear went on, did you get a wheel alignment ? Just the two wheels or four ? Was it set to factory settings ? On the print out, does it show the three static angles ? Camber/Caster/Thrust and Toe angle.

You could try finding some flat ground. Mark where your tyres are sitting on the ground. Then without touching the steering wheel, go reverse then forward several times. See if they finish on the original marks. Take it tyres pressure is even. Do you know if this car has ever been in a crash ? did the owner mention when this first started.

We put a couple of sets of drive shafts in the Caddy and it would come good for a while. If my memory is correct?????????? It was the diff carrier that was the problem? Something about it being riveted together?

Had a similar issue on a car once after tyres were fitted. Worth checking the indicator line as some of these tyre fitters don't know that a tyre needs to be fitted concentrically ( big word) . My problem very similar, tyres reseated by someone who didn't use a guide dog to come to work and problem fixed.
