Squealing Front Brake

Leon_s · 10-06-2008, 09:36 AM

Recently I notice that my left front left brake is squealing when traveling slowly after a short stop. Can anyone shed some lights on this?

thanks

If it's during braking it could be a worn brake pad. If it's after you have released the pedal then it might be a sticking caliper.

when the pedal is released. How do you fix a sticking caliper?

It's either from corrosion or contamination from seal failure if indeed the caliper is sticking. You have a choice of rebuilding or replacing. If it's not bad, a rebuild will work fine. You don't say how many miles on it. You need to do some more investigating to determine your options. Best of luck.

my car has 40k kms on the clock. I haven't done anything to the brakes yet since the day I bought it (abt 8000kms ago).I'll have it checked asap

Consider that you only have 40k km, about 25k miles, I would recommend to try some tlc first.

- If the pads are getting thin, replace

- Use some anti squeal paste inside the new pads

- You could change the rotors too but it's about $80 a side I would guess. Some turn the OEM ones... I don't, I like to get fresh ones when I change pads.

- Clean and re-grease the two caliper pins. Consider "upgrading" to solid brass guides and new pins.

- Inpect brake lines and brake pad sensors, replace as needed.

- Inspect and adjust parking brake assembly
(Don't forget to dissengage the p-brake when taking off the rear rotors...

- Flush the brake system (since you should consder bleeding the brakes anyway, just do so a lot and thus replace the brake fluid) You can have some one pump the brake pedal or just do what I do; pressurize the brake reservoir with one of those pump canisters..

Just my suggestions.. maybe just change the pads if they are worn as a first step..
