Rear Brake making strange noise?

so you've replaced the pads once then; were the caliper slider bolts cleaned and lubed when putting everything back together?

not quite sure, but I have been running with the same "new" pads for 30.000 miles, installed by a local mechanic, with out issue untill now..

Caliper slide bolts sounds right.

Cant think of much else that would cause it. cars nose dive slightly under breaking, and when you lift off the brake the rear end 'drops' back to normal. could be a squeak from the suspension i suppose?

Would this appear all of a sudden after 30k miles on the new pads..?

Should I run to the mechanic to get this caliper slider bolts cleaned and lubed ??

Thanks,

i would if i was you. it's possible that the they still had a smidgeon of grease left but even that dried off and now they're sticking, causing noise back there. a small can of brake parts grease is a few bucks, it only takes 30 minutes to take off wheel, the two bolts holding the caliper and pulling out the sliding pins; degrease them first, put new grease on, slide back in rubber boots, put caliper back on and re-install bolts, btw those caliper bolts are one-time use normally, torqued to yield and should be replaced every brake job. ask your mechanic if they've been replaced, just to see what type of quality work he usually does.

what's the harm? overheated brakes, leading to faded brakes, leading to boiling brake fluid, leading to no brakes. or maybe not so tragic, just an early pad and rotor changed due to drastically shortened lifespan (heat kills pads) and warped rotors (heat causes that too).

not trying to be a messenger of doom.

it would be well worth it for you to get some tools, which you'll use more often than you think. plus the satisfaction that you will have fixed things yourself.
