1. Check your front rotors for being silk smooth
2. Take your truck to a lightly dusty area where you can force a slide without leaving marks and see if your rear brakes are working at all
3. Check fluid level in your mater cylinder for improper levels
4. Anything further...email me

My rear brake pads and rotors have worn out in 1 year and the front brake pads are the original and don't look worn at all. My sub has 150K miles


Its possible. There is an equalizer valve that balances pressure to the 4 wheels.
Two other possible causes are a problem with the parking brake, or the front rotors and pads are glazed and not providing any friction.

Metal on metal noise when driving. Sounds like brake noise when brake pads are in need of replacement. Sound goes away when the brake is applied. Car only has 20,000 miles on it (2006).


Hello tgiro7: My name is Roger and I will help with your question. The fact the noise goes away when stepping on the brake pedal says the problem most likely is in the brake area. The pads could be worn out even at 20,000 miles.If the noise sounds like it comes from the front remove the wheels and check the front pads. If the pads are bad most likely the rotors are also bad.Same would apply if the noise emits from the rear. When you have the wheels off check to make sure the calipers will slide in and out on the mount pins. Should they be stuck on binding the pads will wear excessively and prematurely fail. The calipers must move freely on the pins. If you drive with your left foot on the brake pedal? The amount of pressure required to apply the brakes and not stop the vehicle is 1 to 2 pounds of pressure. Wont turn on the brake lights but will put pressure on the calipers. This in turn will wear out the brake pads. Another thing to look at would be an out of adjustment brake switch. Reach down and grab hold of the brake pedal. Give a firm tug on the pedal. Should you feel the pedal give and hear a click or two the switch was set to deep and holding the brakes on.
Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

Rotors keep warping


Could be a number of problems. Here are a few.

Defective Brake Pads
  • Brake pads that are defective and/or incorrectly installed can, over time, cause brake rotors to warp and become damaged. Brake pads are responsible for squeezing against the spinning brake rotor, an action that causes a vehicle to slow down or stop. If the brake pads are bent, misshapen in any way, or aligned and/or installed abnormally, they can exert abnormal pressure on the brake rotors, a condition that can cause brake rotor warpage over time.

  • Abnormal Brake Caliper Action
  • An abnormal or malfunctioning brake caliper can result in brake rotor warpage if the degree of brake caliper dysfunction is severe enough. A brake caliper houses a set of vehicle brake pads and provides the squeezing force necessary to squeeze the brake pads against the spinning brake rotor. If a brake caliper applies too much pressure to the brake pads, or if it applies pressure inconsistently, it can cause a brake rotor to warp over time. Adequate brake caliper action is necessary for optimizing brake pad and brake rotor function.

  • Excessive Heat
  • A vehicle's braking system generates a tremendous amount of friction-related heat, heat that normally gets radiated away from the brake pads and brake rotor mechanisms. However, in cases where excessive heat is generated within a braking system and not dispersed adequately, serious brake malfunctions can occur, which can include brake rotor warpage. A stuck brake caliper, old, worn-down brake pads, or a defective brake rotor can cause excessive heat to develop in or around a brake rotor, which can cause brake rotor damage and warpage.

  • Damanged Wheel Hub Spindle
  • A brake rotor assembly is supported by and rides on a long, slender metal tube called a hub, or wheel hub assembly. The hub is what allows for the smooth, even circular motion of the spinning brake rotor. Designed with a smooth, low-friction exterior, the wheel hub assembly is critical to the proper spinning motion of the brake rotor. Any abnormalities or defects with the wheel hub assembly, including hub warpage, cracking or misalignment, can cause abnormal brake rotor rotation, which in turn can cause brake rotor warpage over time. Normally, a damaged wheel hub assembly is noticed and remedied prior to extensive brake rotor damage, as a severely damaged wheel hub assembly will cause a vehicle tire to wobble and shake.

    1995 suburban the whole truck shakes when i apply the brakes and the pedal seems to pulse as it slows to a stop. I have changed the front pads calipers and rotors. no change ?


    Now, did the mechanic even suggested anything about MACHiNiNG ur ROTOR brake disc before putting those brake pads? U got UNEVEN brake disc and needs MACHiNiNG to equally level the pads grip to the rotor! Do it i'm very sure of it! Taaah!

    Brakes ,in front, act like the brakes are rubbing metal to metal but not all tyhe time....check the brake padsd and they are good


    what you may be thinking is metal is just hard pads,,,or even dry pads? try striping the barkes out and putting a thin smear of "copper grease" on the back's of the brake pads before you refit them,,,,the copper grease stops the pads from screeming when you push the brake's down,,,,only put grease on the backs of the pads dont get any grease on the brake pad fronts!!!

    1999 grand caravan has a grinding noise coming from the front of the vehicle when braking. what could be the possible causes?


    you have to get new brakes as soon as possible. depending on how long it has been doing that you may need new rotors to about 300 to 400 bucks if there al disk. sheridancory@yahoo.com

    2007 F150 Left front brake grind just today. Can ijust replace all pads. No job right now and just want to get fixed for fair price with no BS regarding rotors etc...


    if your strapped for cash i would suggest doing it yourself as you will not have to pay for labour and all that other BS, not sure on prices on pads but if go to a car parts store they should be able to order specific ones for your car and they arnt hard to change that would be your best bet

    I’m assuming you got either the factory original ceramic brake pads or at least a decent quality aftermarket ceramic brake pad, not some cheapo semi metallic brake pad, such as Duralast or Raybestos PG’s.

    When you replaced them did you properly lube the metal to metal contact points on the calipers? Remember, the pads have to be free floating, otherwise they will not properly engage and disengage from the rotors.

    Did possibly some of the caliper lube get on the friction part of the brake pads? Whoops, no friction then. It happens, solution is buy another set, sorry.
    Did you bleed all four brakes? Even though the system was not “Opened”, guess what, it already was every time you touch your brakes. The extreme heating and cooling during normal brake operations, even more so on Antilock Braking Systems (ABS ), sucks in moisture through those rubber brake lines and various other connection points. That’s the first reason why you do a quick bleed of the system. The second is to balance out the four wheel braking abilities, if you don’t, as the front wheels start to slow faster then rear, the ABS system releases the front brakes to maintain control.
