Hi all,

Have recently developed a severe screeching coming from the rear left wheel of my 1995 850. This is usually preceeded by a 'thud'. Often occurs when pulling away from a stop or at low speeds. Pads are quite new- (less than 2 months old). What could this be? sticking caliper? Any advice welcome.

 

OEM pads?
Front or Rear?

 

Are the pad retainer springs in good condition?
Installed half-size shims?
No dead animal stuck onto the left rear wheel area?...[8D]

Hi all and thanks for your feedback.

No roadkill stuck to the left rear...

Retainer springs/brace seem fine.

The pads are good quality from German & Swedish. Could it be a sticky (randomly engaging/disengaging) caliper?
A Bmr enthusiast pointed out that his 325 had very similar symptoms, and his was due to a siezed caliper.

Is this something any of you guys have come across?

Or is this a 'bit of grease on the backs of the pads' job?

Thanks...

 

The thud you describe makes me think it is either a sticking caliper letting go, or a loose pad due to a bad retainer spring/wrong missing shims

 

Did you grease the backs of the pads pretty well?
