I replaced my front brake pads and rotors, and my rear brake shoes and machine drums two weeks ago. When I brake, as my car is about to stop there is a squeaking coming from the front brakes . The sound also comes if I brake hard. I realize that sometimes new brakes may make sounds. but its been two weeks, and its not the normal brake squeak, it is an intermittent squeak depending on the speed of my tires.
most likely a cheap set of pads/shoes were used, and or they weren't greased correctly when installed. most cheap shops or big franchises won't grease brakes, but i'm a firm beilever in it. another possibility in my opinion would be that the shoes were installed incorrectly or maybe not adjusted after installed. good luck.
Hi you have a twin master cylinder which has two hydraulic circuits when the brake pedal is pushed hydraulic oil is ent down the pipes to the brake shoes slave cylinder at the rear and to the brake calliper on one from wheel as it does to the other side so braking takes place release of the pedal removes the pressure so the cylinders retract. simple as that.
sometimes as you brake the brake pads will and can move inside the caliper(this is obvious if you remove the pad and the paint is worn off the steel backing of the pad)causing a squeal and even whilst driving(no brakes used)to rectify the problem there is a product called brake anti squeal it is like silastic the goes onto the back of the pad creating a insulating layer so the pad is not rubbing on the caliper.hope this helps
