Brakes or Suspension

biggor · Post by **biggor** » 05 Apr 2004, 02:08

After leaving my car sitting for three weeks, as expected the brakes were a little 'sticky' to begin with although this appears to have cleared. What I have noticed is that there is a noticeable high pitched squeel from the rear passenger side when I turn left round corners as the weight is transfered to the drivers side. I assumed it was still brakes playing up however when I get in or out the car the noise can sometimes be heard as the car moves up and down. Is this likely to be suspension related or brakes? any ideas?

Hi, because the handbrake works on the front wheels when you get in or out of the car it is the rear wheels that turn slightly as the suspension levels out. So it is quite likely that the squeal on braking is being caused by the same disc brake.
If it does not clear up soon I suspect you will have to strip them out to clear any rubbish and or rust flakes. They may also be sticking a bit as you suggest.

I've got exactly the same problem as, the squealing when u turn to the left, I've stripped the brakes down took out a bit of debris but it's had no effect, someone's suggested that it's corrosion where the calliper joins the arm, tell you the truth I'm a bit of an amateur so I'm not sure...it just sounds expensive!

Could be the infamous rear trailing arm bearings.

What car is it? If its a hydraulic Citroen the rear brakes may not operate at all at normal height if the car nas no load. Try putting a load in the boot and taking it for a run and see if the rear brakes polish up a bit.
(Alternative - raise the suspension which should inrease the pressure available for the brakes and drive it vey slowly and apply the brakes with your left foot. This should get the rear brakes to operate and polish the disc.)

Another way of getting extra weight over the rear axle is to reverse quit efast then slam on the brakes.
I didn't say it was a good way, but if you have an empty runway or something....

Sounds about right about the corrosion. Rear left brake squeal on my Xantia was cured by removing the caliper and cleaning the corrosion from where it joins with the suspension arm. The corrosion doesn't happen evenly so you end up with the caliper at an angle from the disc (mine had about 3mm of corrosion behind it at one side and none at the other).
