My 1998 Toyota Altezza Rear-Wheel Drive is making noise when I'm coming to a full stop. So when I apply the brakes and the car slows down to around 20kms or lower it makes like a squeal, sounds li

The right front weel makes trouble noise when you drive

A grinding or rumbling noise can also be symptoms of a wheel bearing or constant velocity joint in a driveshaft. A worn wheel bearing can also cause a 'whistling' sound (as can a worn CV joint).

A grinding noise with brakes is either worn pads causing metal to metal contact on the brake disk/rotor, or the brake backing plate catching on a spinning rotor ... or a loose/missing anti squeal brake shim (they stop the pads from rattling and vibrating).

However, as you say a mechanic has looked at the brakes and can't find anything wrong .. I think I would begin to suspect a wheel bearing or constant velocity joint on the driveshaft (front wheel drive cars).

Do you have all wheel drive? If so, I suggest inspecting the rear end.

possibly a wheel bearing or c.v joint .

First of all your going to need a bleeder wrench to open the bleeder valves located on your brake calipers correctly without crushing or damaging the nipple. First make sure the brake fluid is at the max capacity in the master cylinder. Then have someone pump the brakes several times and keep pressure of them whie you loosen first the Right Rear, then Left Front then Left Rear then right front. As you move from wheel to wheel don't forget to tighten the wheel your currently working on first. Keep doing this sequence until the brake fluid is coming out clean and with no air bubbles. Don't forget to fill the master cylinder bake to max full. You may have to pump your brakes until firm before driving just to be on the safe side.

is this the front brakes doing this?? or the rear?? i would recomend changing pads and rotors and drums(rear) and shoes(rear)

could be the ABS sensor contacting the slotted sensor ring. just behind brake backing plate.

Did you use exchange shoes, and were they oversize? The shoes must be adjusted very close to the drum to prevent this lock-on from happening, maintain a high brake pedal, and reduce wear. If the adjusters won't bring the shoes out to lock the wheel when adjusting, they are too small.

A word about adjusting drum brakes...Move the adjuster so that each shoe locks the wheel, then back off till you can turn it more or less freely.You may have to have someone stab the pedal for you the center the shoes as they are backed off. You should hear and feel the drag of the shoes. Do this for all shoes on both wheels.

Sounds like a wheel bearing.

Ok, it could be a few things, 1. bad break caliper. 2. if you have ceramic breaks, it could be a cracked brake pad, and if they are not ceramic they can still be cracked. 3. if you drive a lot then it could be that you need new breaks again.. 4. also have your back breaks checked along with the front ones..
