Ya well i had a bad problem with my brakes sticking about 2 months ago. So i fixed that by getting new calipers and bleeding the brakes. Then a bout a week later a metal on metal squeel noise...terrible noise! So what can it be? The pads looked ok when we had it apart, but the whole truck still shakes bad and my mpg is still at 13..there is a problem somewhere.
What could it be?

 

how do the rotors look???

 

They arent too bad, i mean there are small little bumps, but no deep ridges, or gashes from metal.

 

little small bumps? i might be thinking different than what youre describing, but that doesnt sound right. have you tryed getting the rotors turned? replaced?

 

i dont really mean bumps, i just couldnt find the word for it, more like ripples, but not extreme, nothing that i would think would cause a problem. But why would that make a metal squel noise?

 

good point ;o) i've actually been having a very similar problem with my brakes. its a nasty metal/metal noise, and some braking roughness, but it only seems to occur when my brakes are really really hot...

i wonder if it could have anything to do with severely degraded brake fluid? maybe i'll change mine and see if that helps, of course i don't know how that would fix the metal noise.

 

if your rotors/pads get too hot, it is possible to glaze the rotors. I have never heard of this causing a certain noise, but very poor brake performance. I warpped my stock rotors before I had 1,500 miles on the truck, manufactures use the cheapest stuff available these days, but still that wouldn't cause the noise problem, just a pulsating pedal. Stupid question, but did you look into the rear brakes as well?

 

Ya thats exactly what mine does...makes noise once they get hot. I dont understand...but its killin me.

 

If you plan on flushing out your brake fluid, I would recommend the vavoline syn-power dot-3/4 brake fluid. For some reason, I have found that fluid to give me a slightly beter pedal feel than others that I have used in the past.

 

Alright..i might try that^^Thanks!

 

could severely degraded brake fluid/boiling fluid cause rough braking?

 

It is possible, but unlikley considering the signature states that he/she has a 2000 model year vehicle. Givin, I do not know the conditions in which the vehicle was used, but for the brake fluid causing the problems, it's possible, but unlikley.

 

i was asking for him and me both.... because it seems like were having a very similar problem ;o)

 

See, i have changed my calipers in the past 3 months, and i of course had to bleed the brakes and add more fluid. My brakes started to squel after this, so im goin to get my rotors turned and change the pads and see if that helps. The problem is is that its gonna take a long process to get my rotors off.

 

Brake jobs should be done completly the first time. Putting new parts and not considering wear on other parts will lead to failures in the future. Brake pads/shoes and rotor/drums turned and repacking bearings are inexpensive just a little more time consuming..but pays at the end.
