On my 03 nissan altima my brakes sqeek and grind, but niether of my brake pads are low. What might be the prob

Answer 1

A number of things can cause this, type of pads (metallic), rotors glazed or rough, hot spots in rotors, warped rotors. These same problems can also be with drum type brakes. Not turning or replacing drums-rotors when brake pads or shoes replaced. Their is an anti squeal compound you can apply to backs of pads which some times helps.
Hope this helps

Answer 2

Brake squeaking or squealing can be a function of the type of pads that were used or the absence of anti-squeal backing plates on the shoes themselves. Annoying, but easy to fix. You can buy anti-squeal gel to put on the back of the pads (between the caliper and the backing plate, or buy new anti-squeal backing plates. Or, if you used metallic pads or some cheap organic pads, you can switch over to another variety, ceramic for example, which are available for many cars today.

The grinding is another issue. More often than not, when brakes grind it is a function of a bad caliper (on disk brakes) or a bad wheel cylinder (on drum brakes). What happens is that the piston inside the caliper or the wheel cylinder and/or the wall of the cylinder itself gets corroded and rough and the piston does not move smoothly when you actuate the brakes with the foot pedal. If the corrosion is very bad, it may be hard to press the pedal down. It if is modest it will engage the brake properly, but offer too much resistance to allow the pad to retreat when you let off the brakes and this can create a grinding noise and lead to premature failure of the pads, as they will remain in contact with the rotor surface and overheat.
Sometimes you will see evidence of this on the rotor itself which may turn bluish-black from the scortching.

With brakes it is really hard to say without seeing them.

You could have shattered the pads - from them being hot from braking and driving into a water puddle.

Warped rotors - you'd feel the wheel vibrate when you brake.

There are squeal tabs on all brake pads - this is an indicator that the pads need replacing.

Neglect that and you'll soon be grinding the backplate and rivets to the rotors - that will gouge them and render them junk - I've seen it a million times.

Answer 4

Bleeding order is stable rear then Left front. next Left rear then good front. vehicles with Anti Lock Brakes disconnect the battery. sense if there is any play on any of the wheel bearings. Play pushes the caliper pistons into the calipers and reasons the could soak up that better holiday. present day vehicles with ABS the brakes have a tendency to be sort of comfortable. additionally it takes numerous days for the hot pads to placed directly to the rotors that still makes extra brake gadget slack.

Answer 5

sand! If you drive/park on dirt or sand it will get in between your pads and rotors. Also, the quality of your pads makes a HUGE difference! My pads were BRAND NEW and squeeked and left bad dust, because they were cheap as hell!
Another thing to keep in mind! Brakes will start making noise when it's time to change, it's an indicator. And usually at about 1/4 it's time to change.
You could try taking the shoe off and examining your pads and all yourself.

Answer 6

You could have a pebble logged in the brake pad. Happened to me few times. You can't see it unless you remove the pad and look at it.

Answer 7

i had the same problem on my van and check the sensors on the brakes they might be bent in to far.

Answer 8

your rotors could be warped. you may not be able to tell just by looking at them. i'd advise taking them to a shop and have them check to see if you need to have them turned or if you need new ones

Answer 9

are you using semi - metalic pads ?

Answer 10

wheel bearing is bad...or cv joint.
