96 Series Ii 33 Gtst Shuddering And Screetching

[hks33]

hey sau,

love this site and appreciate everyones help alot, i recently have got my brake pads machined and replaced but for some reason when i apply sufficient force to the brakes i can hear like a screeching similair to the sound of worn pads... its only coming from the front discs im fairly sure they arent worn allready and not sure what it could be since i have recently changed all four

regards chris

i forgot to mention the car shudders and shakes when slowing down and force is put on the brake

[DVS JEZ]

the discs are warped or the discs mounting surface has rust on it causing it to not seat perfectly flat

, did you get a mechanic to replace the pads and machine the discs?

take it back and ask them to check it for u. they shouldnt charge you anything if they were done recently.

other than that if they were not bedded in correctly they might be glazed and warped from any hard braking you have done.

The anti squeel shims haven't been reinstalled on the new pads.

hopefully there not warped there not rusty either because had all 4 replaced and machined recently its just the noise the front two or front one which is a problem

Did the brakes work ok when you first drove it after having the pads changed and rotors machined?

[hks33]

i guess they seemed to be

[Dobz]

If they were working ok ei. not shuddering or screeching before then they started it would be due to improper wear in of the pads. If you don't wear the pads in properly they glaze as DVS32R said. Glazing makes them squeel, then over heats your rotors causing them to warp and gives you shudder.

sounds like a reasonable explaination... thankyou soo much that was the answer i was looking for

high regards chris
