Default What? Squeaky brakes?

Just had my rears replaced and now have a squeaking after their hot as I approach a stop. Anyone else have squeaky brake syndrome? Is there a "break" in period? ---no pun intended :-)

Who and what did you have put on?...Dealer's Brakes or some other's?

IMPO..sounds like some cheap POS pads or some half-*** job or both..i.e., lacking vibration shims, no cleaning of calipers/mounts, lacking lubricant, a number of things causes brake squeal...Mostly cheap ones do it.

Yes, break in is required for brakes.

Many people don't apply their brakes hard enough to break them in properly and squeal results.

How long ago were your pads replaced? Did you also get new rotors ?

Did you use Jaguar pads?

Did you use a competent shop?

Dealer did the work 3 weeks ago. OEM pads. Rotors were fine so did not replace them. 2010 with 27k on the clock.

Better to have replaced the rotors. They likely won't last the full new pad life but too late now.

Trouble with reusing rotors is they need to be skimmed to ensure the new pads evenly deposit material on the rotors or smoothest braking. Skimming reduces rotor life.

I recommend you go out onto a conveniently lightly travelled road and perform a series of medium brake pressure braking events from highway speeds to bed in the new brakes. Don't get the new brakes hot just work them reasonably hard and smoothly and consistently to bed them in. Then drive normally for at least 500 miles. Then go out and hammer the brakes hard for half an hour or so. That should get rid of the squeal.

Google Stop tech brakes and read their technical papers. They're good.

Thanks for the tips. Will definitely exercise them.
