Disc brake squeeling problem

Parnelli_001 · Mar 12, 2002

Does anyone know how to fix a front driver side squeeling in the brake system somewheres? i know disc brakes are prone to noises, but this one sounds serious and hasnt gone away. The disc/brake pads all are in very good shape as i looked at them and the rotor isnt scored or anything. however at about 20-60 kms i have a loud squeak that goes, dies, goes, dies about every 2 seconds depending on the speed. (faster as i go faster) What gets me is when i touch the brakes it goes away completely, when i let off it comes back immediately. WD-40 didnt solve anything and there arent any rocks or anything stuck in it. HELP!!!

could be a warped rotor or breaks have a little thing called a squeeler and it makes a squeeling sound when yer breaks go down they are still ok but the break company wants to make as much money as thery can so they put the squeeler at about 40 percent pad left so all you have to do is get a screw driver and dend that little tab... but yer squeel is intermitent so my guess would be warped rotor ... sorry if i'm no help but check that and see...

sounds like bad pads some new ones will squeak try putting better ones in.And dont oil them that will wreck them forsure

You could try some disk brake quiet. Its kinda like a glue you put on the back of your pads. It stops them vibrating which some times makes a squealing noise.

maybe the little squeeler indicator is touching.
or whatever the thing is called its a small peice of metal on the pads.

just a thought

WD40 and breaks don't mix! I think this will cause premature break down of the break pad material, quality raybestos or wagner pads will not squeek...I had the same problem on my wife's exploder, used some blue goo, brake quiet, and it went away!

Hit it with a BFH until it goes away (or falls off).

No seriously though you might have dirt or mud caked in there and it makes ungodly noises. Mine did it for weeks until I finally got off my ass and took it all apart and pressure washed everything.

I guaruntee your caliper pistons are shot. I had the exact same problem on my rig. It went away when I got some rebuilt calipers. So either rebuild your existing ones or trade it in as a core.

Hey guys, thanks for all the great suggestions, however i dont like that it means more work on it. i did take them apart and couldnt see anything visible such as mud and such caked on, but its worth another look. that brake goo is a good idea but with the brakes squeeling i know there is a problem, i want to fix it and not pro-long it. but it does seem like thats what i will end up doing anyway

How is it that one goes checking the caliper pistons? what really got me was that the brakes squeeled only when they werent under pressure. If they were worn down shouldnt they squeel when they are applied?? the noise always goes away when i push on the brakes, but comes back when i take my foot totally off the brake pedal. i'll check your suggestions and get back to ya'll, thanks

Where the pads dont contact the rotor, there is usually a build up of rust. This could be contacting the pad and making noise. Just sand off the rust. Dont know about Nissans but most front pads have a anti sqeal shim on one side of both pads. Also check the anti sqeal springs or clips , could be broken, missing or too loose. Most likely its rusty rotors.
