hey my front left caliper squeals somtimes when im goine as soon as I hit the brakes at all it stops, when I got it saftied my mehcnaic didnt take the wheels off cause he said he could see through the wheels that the brakes are new. he said the problem is caused by the fluid not returning all the way and is common with these cars? any ideas how to fix it?

 

There could be many things causing the noise, cheap non OEM pads for one. Disc brakes are famous for noise, the rotors must be very smooth and good pads must be used but for starters you could take the pads out and sand them off out on the cement driveway while making figure 8's until the surface is completely rough looking, no shinny polished varnished surface allowed, do a good job.

Make sure all the anti vibration clips are there, you will need a parts diagram to be sure of this, there are links in the search files here to Honda dealer parts house. You should lube the proper areas and this takes experience and two types of special disc brake grease for the two areas that require lubed, NOT ON THE FACE OF THE PAD.

After all this work it may only last six months so in order to save some money be prepared for some brake experience and at the same time remember, this is the only thing stopping you from running into the back of the BMW so if you are not comfortable then take it to the shop.

As for what your technician said, if fluid was not going back up properly then your rotor would get hot after a drive around the block or a few drives around the block without using the brake pedal, go for a good drive, do not use the brake pedal, gently use the emergency brake handle to slow down and stop so as to not heat up the front rotors through normal brake usage. After some driving time put it in park, get out and feel the rotors on the front and compare the temps of the left and the right, if the side he said is hotter then the caliper is dragging from a bad caliper or a colapsed hose internally or improper installation of the caliper overall.

 

k thanks, yeah somtimes they squeal alot when reversing, ill try what you said

 

hav u checked the rear pads for wear???the fluid not returning?? common?? no such thing ,,, if it is the caliper or piston sticking then it is ot common , first off make sure it is the frt, lift car up and spin the wheel see if u can hear noise that way ,,remove wheel and chk to see how freely caliper slides ..make sure the inner pads is not hitting indicator,, sometimes pads wear uneven , one can lok at the outer pads and look ok but at the same time inner pads is hitting the pad wear bar

 

NOT COMMON is correct but has happened, fluid being pushed into caliper like normal but will not return back to master cylinder. open the bleed port and caliper releases, change brake hose and problem gone in a few cases, cut the hose open and the inner wall had colapsed acting as a check valve.

I do like your analysis of this job though with uneven pad wear, this should require a caliper change or rebuild if that state allows rebuilds by regular folks.

 

might not be the problem but did you check the caliper bolts? If those rubber boots that go on at the end arent seated right, dust/dirt/water/grime can get in there and then lock them up such that the caliper won't move right....happened to mine

 

I got some service record from the previous owner and the whole rear system was changed last year, but theres a note that says front calipers hard to depress, ok ill try all the things you guys mentioned
