I been having this troublle for about 3 months it annoys me everytime I drive the van , the first thing in my mind is the brake pad, second the wheel hub. So bought this two parts before pulling down just in case. I take off the two bolts holding the caliper to get get access to the brake pad and try to clean it first, I notice that there are foreign particle in between the groove of the pad so I carefully cleaned two pad with the tip of a file, I assembled it and try to drive around and whalla no more squeaking.
Could also be the brake "squealer" is telling you that the brake pads are worn down and in need of attention.
Usually a sign that the "wear indicators" are rubbing against the rotor (as designed) to let you know that brake pads need replacement
need new rear brake pads.
If you are driving and you hear a high pitch squeeling/screaching sound but when you apply the brakes the sound stops your brakes need replacing, this is called your brake squeeler.
The brake pads have a squeeker plate on them. If you recently had a brake job, they removed the plate and did not replace it. I
The low brake indicators on the brake pads are squealing. I highly recommend you have the brakes checked out.
The brake pad squealers are warning you to have the brakes serviced soon.
Typically disc brakes are known for being squeaky as opposed to drum brakes (although drum brakes can squeak, it's unusual) so I'll limit my answer to disc brakes. Disc brakes generally squeak for one of two reasons: Either they are resonating against the backplate of the caliper (a high-pitched vibration) or the brakes are so worn that the wear sensor is rubbing up against the disc and is making the noise. In the first case, when new brake pads are installed, there are a few ways that pad manufacturers deal with the potential for squeaky brakes: one is by using a gel that semi-hardens and is applied between the back of the brake pad and the caliper which acts as a dampener. Another way (and I'm sure there are more...) is to use a special metal or fiber intermediate shim between the brake pad and the caliper which also acts as a dampening device. If you brakes are squealing and driving you nuts and you just had them replaced - take them back to whomever replaced the pads and have them fix it - they probably left out the important device that prevents the squeak/squeal. If you are experiencing squeak without having recently replaced your brake pads: This is the other reason why your brake pads might squeak: nearly all disc brake pads have wear sensors. A wear sensor is a little tab of metal designed to squeal when the brakes are applied IF THEY ARE WORN OUT. If you brakes are squealing or squeaking, have them inspected.
worn pads change your brake pads and get your rotors machined while your at it
If your brakes go out while driving, first shift the vehicle into neutral and then apply the emergency brake. If neither of these slows the vehicle, turn on your safety lights and get into the right lane.
squeaky sounds that go away when you push the breaks are most probably the indicators on your brake pads that squeak to let you know that they are getting worn out and need to be replaced soon also dirty brakes will chirp while driving, a thorough cleaning and lube of the proper parts usually cures this There are typically metal tabs on your brake pads that are meant to squeak when your pads start getting low. It is possible that is the cause of your squeak, check your pads, or have a mechanic check, as this is a good possibility, however not a definite.
remain calm and continue driving in the same lane. Begin to apply the manual emergency brake with your hand, lightly at first to determine the strength. You dont want to lock up the brakes, so apply the emergency brakes in spurts and make your way to the side of the road.
(Harmony2k3) If you have the following issues then I would have them checked: (do they squeak every time they are wet? do they squeak at all when they are dry? when you push your brake pedal is it spongy and go to the floor? do you have to pump your brakes? has it been more than a year since you've had brake service?) If you said yes to any or all of those questions then I would have them looked at.
