Shaking on Braking - The Unofficial BMW M5 Messageboard (m5board.com)

BURTON · 11th April 2005, 17:37

Yesterday I got bad shakes while braking! I know this should not be the brakes as I have just upgraded them so I know that these are in good sted. I used to get this problem but had gone away and this was the first time for a few weeks that it had been back.

Anyway I just ordered the bits from BMW 500 pounds later!! Ouch!!!

Ahh the joys of owning a expensive M mobile.

But hey I need to do this for my trip to the Ring and Spa next month! Also would like the Touring ARB and new Springs. But they can wait at the moment.

Thanks for reading...

Hi Burton

My recently acquired six-speed M5 had the front floating discs replaced one year/5,000 miles ago (genuine BMW parts) - it was vibrating real bad when i test drove it, bought it anyway - turned out the discs were warped. The local dealers here replaced them under warranty, very helpful chaps! You may want to investigate if yours are warped too?

Cheers,
David.

Burton, There are lots of things to check. On installing new rotors make sure to thoroughly clean the hubs where the rotors contact them. If there is dirt or rust there it can cause the rotors to act as if there are warped. Found this out on my old E30 318is. The other thing to check is the control arm bushings. Mine were worn and it shook and made a clunking sound under braking. Hope you get this sorted for the Ring and Spa trip. Sounds like a fun time.

Think the originals are sided so if installed wrong will heat up prematurely and can warp

just my two pence

Steve, you missed the bit of Burton's post where he mentioned that his brakes have been upgraded. His M5 doesn't have BMW brakes any more, it has AP 6-pots.

Then my reply is void

Sorry never knew about the AP`s

Thanks for the replies.... its the first this has done it with the APs on. You get her straight and she is fine braking on the left side and she shakes. Also noticed she pulls to the left!
