Brake issue :-( Help needed. Rotors or something else?
 

Noticed that steering wheel shakes when brake only
Also very noticeable when stoping down the hill
Car pulls to the left a little when braking if i let go steering wheel completely at fast speed,but it stops straight if i hold steering wheel
Makes sound sometimes,if i brake slowly at low speeds

I took it to the store they said probably the issues is that all 4 rotors are warped. Will it cause pulling to the left?

My calipers have been rebuilt at 70k miles,but now it is 84k miles.
Rotors have been changed at 65k miles,but pads were not changed.

Sounds like you need rotors but thats not whats causing the wheel shaking, the wheel shaking could be a bad lower control arm or upper control arm. go to some local mom and pop shop and put the car on the lift, ask them to check your front control arms.

Good luck ! =)

any more suggestions?

Whose idea was it to fit new rotors with used pads? Ye gods thats a no no.
The shaking could be warped rotors on the front but the shaking is most likely the thrust arm bushes. These are now available in polyurethane and are far superior.

rotors warped all 4 of them. so will new rotors and pads cure the issue?

sounds like warped/worn rotors to me.........don't know anything about the bushes. My steering wheel shook when I braked trying to slow down from high speeds. Changed new rotors and brakes and now it's fine. The pulling to one side might be an alignment issue.

It will cure the brake shudder but the pulling could still be those thrust arm bushes.

any good DIY guides? hard to do?

Completely off-topic but, sobi6111 is your X5 a sports model with colour coded door handles? or a non sport that has had them sprayed to match? If the latter, did you get them sprayed? were they sprayed on the car or off? is the paint match good. It looks like you have the all orange non- sport indicator lenses hence me asking the question........but actually, after looking more closely they look like the sport model kind. Ignore this....sorry

Sorry to Hijack the thread.

Here is a guide for the bushes.....

As for the brakes, yes, straightforward but fit 2 new pad sensors at the same time and bed the brakes in properly to prevent a recurrance of the warping.

sobi6111: Just a suggestion, could you use a smaller picture for your signature? Using such a large image makes reading threads you post in somewhat irritating since one has to scroll 980 pixels to the next post each time. Thanks!

:iagree:

warped rotors would be the cause, the max runout is .004". when replacing rotors on a BMW x5, the pads are to be replaced as well, I would only recommending using OEM rotors. Here is my reasoning. The X5 rotors are warp friendly, say you replace them from some online vender or aftermarket company, most do not come with warranty. If you install the OEM rotor from BMW, now your covered for the next 2 years with parts warranty including labor. If bmw is paying to replace the part, they are going to pay the Labor. I have a customer who always brings his car to us every 1.5 years with brake shimmy at highway speeds. Every 1.5 years he gets new front rotors and pads free of charge. Because he purchased the parts from BMW. We torque the caliper bracket at 110NM and the Wheels to 140NM. and they always seem to warp no matter what. So go with OEM.

Whilst it is very nice getting new discs and pads each 18 months, doesn't it say something about the quality of the parts? I would rather replace the discs with a reputable brake manufacturer, ie Brembo or Zimmermann and fit OEM pads.

If the discs warp that often there is either a problem with the quality of the part or the vehicle is being driven beyond its design criteria.
