Anyone ever had a brake rotor out of balance?
#41
I thought I'd add my experiences on this topic.
I had a '03 XK8 on which the PO had fitted new discs just before I bought it. I fought with wheel vibrations until a fellow owner suggested I try on-car balancing (which is pretty hard to find a shop for in the UK) and that solved the issue right away, the operator suggested rotor balance.
Anyway I recently changed cars to an '05 XKR with Brembo brakes and she needed new rotors. I decided to buy aftermarket rotors and took them to a local balancing specialist (he works on things like Nascar brakes, Rolls Royce cranks and other cool stuff) and paid him £200 (around $300) to have the new discs balanced.
All four of them were way out of balance, to the extent he said it would have been impossible to balance them out by using on-car balancing.
I've not yet fitted the new discs but sure am glad I had them balanced.

I'm going through this exact same thing. Installed cheap rotors that were WAY out of balance. Bought another set of supposedly
balanced rotors and is much improved but have slight vibration. The first four rotors are at the machine shop now to get balanced.
I bet they are really way off and the second set is off but less severly.

I could understand the shake in the wheel not being any different when swapping the tires L-R but when I moved the rear wheels to the front? That one has me scratching my head. I suppose it's possible that I have bad tires on both ends but it seems unlikely.
The engineer part of me just wants to know where it's coming from and it's become a matter of principle now. No mere machine is going to defeat me!
I'm going to call some auto machine shops that can balance flywheels and pressure plates and the like so see if they can check a rotor.
Surely it will cost less to check than than to buy a new tire(s) as an experiment.
