83 944 problems
So i have 3 issues that i can't get to the bottom of
1. I have one brake (Rear passenger side) that squawks whenever i drive anywhere... i've replaced the caliper, pads, and bled the lines repeatedly, but the squawk continues and it seems to be getting worse and wearing the brake pads funny... i can't figure out what im missing unless theres an equalizer valve somewhere that i forgot to loosen when bleeding?? 2. in addition to # 1 my brakes seem to be dragging (all 4) not enough to seriously inhibit my driving, but enough so if i leave my house after just polishing my wheels and drive the 3 miles to work when i stop they are completely coated in brake dust... again i've bled them completely, change pads rotors and calipers but still they drag... 3. Under hard acceleration (before my brakes started acting up) i get blue smoke coming up through my shifter area, if i back off the throttle it stops, but if i get above 4k rpms its starts pouring in thick.... pull over and check and don't see anything smoking anywhere, no fire, no major fluid leaks onto the headers nothing can't figure it out for the life of me Any advice you guys have is greatly appreciated... |

1. take some 80 or 100 grit sandpaper and sand the rotor face down. then brake cleaner it. then put some brake grease on the backing plate of the pad.
2. bigger problem for you. brake drag = caliper stuck. u need to take em off and rebuild em or replace em if need be. 3. your engine is leaking oil onto the header. most likely rear of cam tower or head. |

a better description of the noise would help. brake drag can be caused by your calipers sticking, the pusrod out of adjustment, a few other things. how does your brake pedal feel? any pulsations, is it hard to depress, does it feel springy/spongy? did you touch the drum brake part in the rear?

Thanks for the responses, The Squawk i figured out, turns out there was a spacer on the back of my brake pad that wasn't supposed to be used with the new ceramic pads... bug duh on my part, but after i pulled it out all it got a lot better, still an occasional noise but not anywhere near as bad as before
The whole-car brake drag however i can't figure out i bled the whole car again this weekend after replacing the calipers and they still drag bad enough to coat the front wheels in brake dust in a 3 mile drive.... the Smoke i still can't figure out, i'm not losing any oil according to my dipstick and i don't see any streaks down the motor or firewall, is there anywhere in particular that this happens from? |

weird that there wouldn't be a trail of fluids or any drop in levels though... very strange. Its hard to diagnose for certain too because if the car isn't moving it doesn't happen.

the brake drag is most likely caused by your calipers sticking, pretty simple fix just rebuild the calipers takes mayb an hr to do all 4. of course thats the likely cause, could be a problem with your pushrod out of adjustment or your master cylinder.
