Brake squeak

[chromofoam]

Hi guys,

 

New round here and hoping to get involved with local events etc.

 

Just have a question that I've not been able to solve myself so far;

 

I bought my X-Type from a great dealer who has really helped me with a few small problems (Silverline Jaguar in Stevenage if anyone knows of them?)

 

Anyway, recently the car went in to have an o2 sensor replaced, but at the same time I mentioned a problem that seemed intermittent with the brakes/wheels/steering - sounds like a very high pitched squeak, almost like grit stuck between the pad and the disc, or brake dust or something - the only time I've heard a similar noise elsewhere is from London buses or from cars with anti-vibration shims missing from behind the brake pads.

 

Does anybody know what this could be and do you have any suggestions of how I might fix it? Would a dab of copper grease on the backs of the pads do the trick? A squirt in the mating surface with a pressure washer to remove any debris? (although I imagine 'spirited driving' would remove most of this!)

 

Any other clues? Has anyone else experienced a similar problem?

 

Thanks all!

Hi Alasdair,

 

In general, squealing from brakes is caused by resonance when the friction lining material is clamped to the disc by the caliper. This resonance can be isolated by applying Copperslip to the backing plate where it contacts the caliper & cradle.

Alternatively, you could replace the pads with a better quality pad which should eliminate any noise.

 

Hope this helps?
