brake shake

[cutloos]

Sort of new to this forum. Usually only have to read the other threads to find my answers. I have a tough issue though. When driving around and I hit a bump my brake pedal shakes. I just replaced my shocks with some new bilsteins and this made the problem a little worse. The pedal shakes enough to turn off my cruise and once It even felt as though it did some braking without my help. Any thoughts on what to look at or fix would be great.
Thanks, Great site.


FYI took the yukon in to a known good shop and found nothing wrong but that it was slightly out of alignment. Any other thoughts? Please

Thanks for the help guys. I will get it in to the shop with something to look for now.

Went to the shop with nothing found wrong but slightly out of alignment. Any other thoughts you guys might have would be greatly appreciated.

are your wheels hubcentric or lugcentric? Might have the balance checked on all wheel/tire combos.

 

[cutloos]

don't know the difference of those centrics, but did have the balance checked. No problems there. The shake does only happen over quick hard bumps very smooth driving otherwise.

might get a second shop's opinion on upper/lower bj and t.r.e. imo...just in case.

x2 on that...2nd opinions are a must. I took my hoe to a dealer on something else and 2 mechanics including the foreman drove my truck. "No problem." they said.

Wrong...it was a BIG freakin problem

I´ve had the same problem with some old rims that didnt center on the hubs. Try out some other rims, might help.
