My 2001 v6 pajero is making squeaking noise when ever he brake is applied,all disc pad is brand new,i was wondering if it could cause wear lock pin r guide pin the caliper itself have a minmal play in it whenever you move it. any advise woulb a ppreciate.

If you didn't say there were new I'd tell you to replace the pads as Mitsi's really sqweak when getting low. One idea is that you have something caught inbetween your pads and the rotor like a rock. This can make a noise when brakes are applied. Determine which wheel is noisey and remove wheel and blow clean with an air compressor. Only need a little pebble on the back side to drive you crazy. Might also givce the rotors and pads a spray with some brake cleaner just in case you have some other foreign object on the pads.

the left rear and front left make the squeak whenevr u brake hard there is no noise ,but when just shodow brake pedal u hear the squeak noise which is very annoying, i clean and spray them all up but same thing could it be like a worn lck pin or guide pin cause it ?

There could be anything stuck or protruding in there. Best indicator is your rotors. Do you notice any shiny patches which could be an indicator of what is rubbing? You may try spraying something on the rotors while you have the wheels off (light coat of spray paint) and then spin them up to see what is interferring with them.

Well i tried all that but when the is slightly depress the squeak noise comes in seems as if is the complete caliper moving ,i
'm not sure all i know the noise is killing me .Whenever hard braking no noise , i clean p everything and cannot see whats wrong , is it possible the the guide pin and lock pin can cause noise, i was thinking the disc roto might be warp but i check it and everytin look superfine , i might just take it to the dealer if no solution , thanks for ur respond if anymore info available i would be appreciated.

If I understand you correctly the entire caliper shouldn't be moving when you push on the brake petal. You may have something loose with the mounting bolts, etc. It is not a warped rotor as this will make the petal pulse when depressing.

As you don't know alot about the brakes themselves (no insult intended) you should really bring into a mechanic to check. I'm worried that if it gets any worse you will damage your rotors ($$$ to repair) or worse yet your brakes will fail. Please get looked at urgently before something bad happens and let me know what you find out.

Jim

thanks alot for the info will keep u inform ok ASAP

When the pads were fitted did you fit the anti-squeal shims to the back of each brake pad?

only one had on a single shim on one side of disc pad, is the the missing shim could be the cause of squealing sounds?

It might rattle or squeak a little but nothing as you described above. Certainly you caliper will not move because of a missing shim.

hey guys i change the disc pad clips and all is well no more noise!!!!!!!!!!!!!!!!! i'm happy now driving in comfort now
