Also, did you:
- re-check all wheel bolt torques? (97 #-ft on 987 IIRC) YES
- remove any caliper while installing? (if just pads no need on '04 986) check caliper bolts? YES
- replace rotors (sounds like no)? YES
- replace any hardware - caliper bolts, retaining spring, retaining pin, etc.? SPRINGS REPLACED
- apply disc brake quiet (like CRC) to backing plates helping pads stick to caliper pistons? YES
- use caliper grease as necessary? YES
- check caliper pistons for leaks and free movement - inner & outer? YES, no leaks
- bleed/flush brake fluid system once complete? No, but I bled them a month or so prior to changing the pads/totors.
- keep an old pad set from each axle around to measure backs against new? NO, it’s been a few months and I tossed them.
Happy to help - need some more input please.
Good luck  |
thx, see my responses above. Brake performance is good, noise only happens at a stop when I lift my foot off the brake I’ve ordered a better set of pads so will see if that fixes the issue, but I removed and reinstalled the pads this morning and everything looks pretty normal. There is some movement of the pad if I push against the spring, but it doesn’t seem particularly excessive. It’s just a loud click when I roll to a stop and let off the brake. Seems to be coming from front left around mc and the wheel, hard to pinpoint, and I can’t duplicate in the garage. Anything else in that area that could cause the click?
Also, I wasn’t aware a brake bleed was needed after pads/rotors changed since the system isn’t being opened other than removing the reservoir cap. I will give it another bleed after putting these new pads in.
