    What is causing a squealing sound when I brake?
    I just had the front brake pads changed. The mechanic said the rotors were fine and there was still about 5cm on the old pads. Squeal was gone on his test drive. 2 miles later they squealed again. Squeal starts most times when I brake into a turn and keeps ...

      Brake squeal is really a high frequency vibration. In disc brakes, it can be caused by vibrations between the pads and rotors, the pads and calipers, or the calipers and their mounts.

      Noise may indicate trouble, but the only way to know for sure is to inspect the brakes. If you find nothing amiss (no worn linings, or loose, damaged or missing parts), then you can try any or all of the following measures to deal with the noise problem:

      Dampen the pads
      Lubricate the calipers
      Replace the caliper hardware (slides, pins or bushings)
      Replace the pads
      Resurface the rotors

      One way to quiet noisy pads is to make sure the pads fit tightly in the calipers. If the pads on a single piston caliper have mounting ears or tabs that need to be bent or hammered to hold the pad in position, make sure the pad can't be wiggled by hand. If the pads have clips, shims or anti-rattle springs, make sure the necessary hardware is in place and properly installed. If you see no such items when you inspect the brakes, do not assume that none are needed. The last guy who worked on the brakes may have left them off. It is always a good idea to look up an illustration or parts list for the brake system to make sure all the required parts are there.

      If the pads are installed correctly but are still noisy, one of the least expensive and most effective ways to quiet them is to remove the pads and install insulator shims on the backs of the pads. The shims, which are usually self-adhesive, act like little seat cushions to dampen vibrations between the pad and caliper.

      Another option is to apply a noise suppressing compound to the backs of the pads. Some compounds harden to a rubber-like consistency to cushion the pads. Another good choice is to apply a moly-based brake lubricant to the backs of the pads. Brake lubricant is long lasting and won't burn or wash off like brake grease can. If applying a lubricant to the backs of the pads, be careful not to get any on the front side of the pads or rotor!


      The same approach can be used on the calipers. Cleaning and lubricating the caliper mounts can also help dampen vibrations to quiet the brakes. Vibrations here can be caused by worn or loose mounts or mounting hardware.

      If the calipers are badly rusted or worn, they may have to be replaced. But in most instances, you can probably clean them up, lubricate the mounting points and return them to service. You may have to replace the caliper slides, pins, clips and/or bushings, though, if there is too much play or looseness between the caliper and knuckle. Be sure to use a high temperature brake grease so the grease stays where it belongs.

    I have replaced pads and rotors and still have a bad vibration when braking
    This problem was there BEFORE I replaced the brakes and rotors.

      Is the vibration coming from the front or rear of the vehicle? Problems like this can also exist within the suspension and steering system. A tie rod end that is worn out as well as wheel bearings can cause vibrations when braking.
      5/22/2014 AutoMD Member
      It feels like the vibration is in the front-end. I just had the car aligned yesterday and they did not mention any issues with the front-end.

    Are there any guidelines for brake rotor replacement vs. just replacing brake pads?
    81,000 mileage. I just had the tires rotated and the mechanic says I need new brake rotors and disk pads. Front pads are 3and4/32nds and rear are 2/32nds. I can see the need for new pads, but what about the rotors? I have no symptoms, warning lights, noises, etc. ...

      If you have no brake shimmy when braking, particularly when braking lightly at higher speeds, then I would say just change the pads and leave the rotors alone, don't even machine them. But, I would suggest you buy the pads from Lexus parts dept and not the auto parts store. Buy the pads and buy the hardware / shim kit also. The shim kits are a separate part. Don't shop price on pads, buy Lexus original pads and shims and you will be fine. You can just do the one axle and do the other another time. Thems the facts.

      Depends on condition of the roters. If they are warn out and machining them will make them thinner, change roters. If condition good, machine them. Just changing pads may be ok for awhile but may warp and give you uneven braking experience. Use good quality parts.

    My brakes started grinding after I had a tire repaired. What happened?
    I took my car to a chain tire/brake shop to have a tire repaired. That evening after my commute I noticed the grinding noise. I drove the car 1 more time and the noise was way worse. I took it to same chain shop (different location). They said brakes were metal ...

      Not sure if the shop that repaired the tire just missed the worn brakes - but having the tire repaired does not cause the brakes to wear metal-on-metal; this condition happens over time and long mileage.

      Check the many on-line auto parts sources, such as; www.autopartswarehouse,, or for the replacement parts. For example, they (RockAuto) list the front brake pads from around $8.00 per axle set, and front brake rotors from around $31.00 each for your vehicle.

      If the warning light 'TRAC' is on - this usually indicates there is a fault with the traction control system - usually wheel speed sensors - since they are in a hazardous location, but I would also expect an ABS error light to come on if one has failed.
      I would look at things like the secondary throttle motor and TPS as these are TRAC only items. Most of the other signals used by TRAC also tell the engine ECU and ABS systems something like vehice speed, throttle input, brake status, etc. If the brakes vibrate when applied, then you may suspect the following; ABS sensor, wheel speed sensor. Have the OBD system scanned for any stored fault codes (for free - at any local auto parts store). There should be an error code stored for TRAC. If not, maybe your trac-off button is acting up.

    Grinding from brakes, intermittent, pads and roters look good, Minamum ware on pads Seems to be from front
    Removed pads and checked rotors both look good. 41000 miles of easy driving.

      Check the wheel bearings and hub bearing assemblies - sometimes the grinding may occur with new brakes and worn / faulty / loose hub or wheel bearings - causing a slight sideways loading of the wheel and brake rotor when under braking conditions.
      Check the many on-line auto parts sources, such as;, or for the replacement parts.
