There are spring clips which keep the pads tight in the caliper. These spring clips are missing, or are broken, or have lost their tension, etc.

2005 toyota corolla squeaky front brakes when braking at 10mph. changed brakes, rotors, controll arm, pad. What else noise is till there?


anti rattle plates are damaged, remove pads clean rear surface apply thin layer of silicon to pad allowing it to dry then reinstall as per std, this will stop the squeak, or replace anti rattles, silicon is cheaper will last the life of pad, but all new pads will have to be treated the in the same manner .

When driving or starting the car i notice when using the brakes it makes a squeaking noise - not all the time think its possibly damp causing it as it was raining yesterday and it happened but no rain...


To address your first problem squeaking brakes aka "brake squeal", is most often casued by one or 2 things: "Pad vibration" or a "low brake warning sensor".

Pad vibation is usually caused by ineffective pad anti-rattling clips & hardware that allow the pads to vibrate at a super fast speed whenever the brakes are applied, thus causing a high pitch brake squeal. To correct this, replace all the pad hardware and anti-rattling clips and make sure you use a quality pad set that has anti-rattling plates attached to the backs of them. Weather conditions do affect brake squeal, that is why it seems to be worse at times.

Low brake warning sensor squeal occurs when your brake pads reach the point of replacement, the sensor attached to the pads scrapes on the rotor which produces a high pitch squealing sound to warn you it's time for new pads.

As far as your second problem goes (a knocking sound), I'll need more information about the problem before I can offer a possible cause (eg. happens on left or right turns, while going over bumps, at high or low speeds, accellerating...).

After a couple visits to our local mechanics for brakes repair of a 2006 chevy siverado short bed reg cab. My rear brakes are the problem first the mechanics changed them out with premium pad then now...


Make sure the mechanic checked the park brake shoes inside the rear rotors, they quite often break away from the lining and get wedged in the rotor, sometimes causing a constant squeal noise. I've also seen the brake pad anti-rattle metal clips become loose and wander in the caliper bracket, they lightly rub against the rotor and cause a squealing noise similar to worn brake pads. They are also very bad for the backing plates rusting out prematurely and rubbing on the inside of the rotor. Other than that he can just try to champher the edges of both front and rear pads to help dissipate the brake dust, from collecting and causing squeak noises.

Rattle in left rear brake when hit a bump, Ithink it is one of the pads


If you are able to make the rattle go away by slightly pulling on the parking brake, then the problem is with the brake pad. Replace pad.

Brake Problem


hi im dave
hope i can help
when you had the rear pads applied and the discs turned was there noticeable damage to the disc surface it sounds like your e brake cable is not adjusted properly or perhaps the braided wires inside the insulation are seperating along your brake cable causing the rear brakes to not be adjsting themselves properly. Every time the parking brake is applied the rear brakes are self adjusted if they arent being applied due to slack in or a broken cable you will not adjust your rear brakes. This would accont for the flutter in the brake pedal as hydraulic fluid is still circulating to compress the pads against the rotor but the pads arent reaching the rotor.
