Is it that both right and left front brakes are binding? Could be a metering valve, but usually it's a faulty caliper that causes the binding. Important to have this looked at. Take car in to reputable service garage for diagnosis. Brakes most important part of a vehcile= saves Lives!!!

SOURCE: how do you compress rear

to compress the rear caliper pistons u must use a very large blade screwdriver and turn the piston clockwise while pushing it in, this resets the park brake screw inside, really tough to do with the VW special tool.

I replaced front driverside brake pads and the caliper will not fit why ?


If the piston was not compressed completely back into caliper, ( I use a large C-clamp,) then the caliper/brake pads will not fit over the Rotor. Also when you compress the piston back into the caliper be sure the brake fluid resevoir doesn't overflow when the fluid returns during the compression process.

Replace my front break pads. I know how to change the pads but I cant get the pad to release from the rotor


You need to use a (C) clamp to depress the caliper into its bore, only after opening the bleeder valve to exit the filthy fluid. Only then can you remove the caliper. You need to free the pressure against the rotor. Not being sarcastic here but if you know how to properly replace brake pads you should have known this.

We are changing back disk brakes. How do you get the caliper to go back inside for the new brakes to fit?


the piston needs to be turned and pushed at the same time. There are several different tools for this.

This one works the best but is also more expensive.

This one is very cheap and may work. Personally not worth it to me.

These will lock into the slots in the piston. Then turn the piston while applying pressure. Because the E-brake is built into the caliper the piston has a mechanism that allows it to ratchet out. Turning the piston while pushing it in will release the ratchet mechanism and allow to piston to be pushed back into the caliper.

I need instructions on how to remove the rotors and replace the front brake pads on a 2004 mazda 6.


Instructions Things You'll Need:
  • Floor jack
  • Jack stand(s)
  • Wheel chock
  • Turkey baster
  • DOT 3 brake fluid
  • Flathead screwdriver
  • 1/2-inch drive breaking bar
  • 1/2-inch drive socket set (up to 21 mm)
  • 1/2-inch drive ratchet
  • 1/2-inch drive adjustable torque wrench (recommended)
  • Impact screwdriver with Phillips head bit
  • Hammer
  • Bungee cord
  • C-clamp
  • Brake clean spray
  • Shop rag(s)
    How to Replace Front Rotors on a Mazda6
  1. Step 1 Park the Mazda6 on a flat paved surface. Apply the parking brake and release the hood latch. Place a wheel chock behind one of the rear tires and open the hood. **** out half the fluid from the master cylinder reservoir using the turkey baster and discard. Replace the master cylinder cap securely.
  2. Step 2 Break the lug nuts loose on the front tire, using the breaking bar and a 21-mm socket. Raise the left quarter panel first with the floor jack and place the jack stand under the left front frame rail. You can lift the right side too or just do one side at a time. Remove the lug nuts and the wheel when elevated.
  3. Step 3 Pry the two plastic caliper slide bolt covers off with the flathead screwdriver and remove the caliper slide bolts with the ratchet and a socket. Pry the caliper off the pads and rotor with the screwdriver and support it to the coil spring with the bungee cord so it does not dangle by the brake hose. Compress the piston of the caliper inward using the C-clamp until the piston bottoms out in the caliper casing.
  4. Step 4 Remove the pads from the caliper anchor by prying them out gently with the screwdriver. Be sure to memorize how they were positioned in the anchor so you can replace them the same way in the event you're not replacing the pads as well. Remove the caliper anchor bolts using the ratchet and a socket. They're going to be extremely tight, so be prepared. Remove the caliper anchor.
  5. Step 5 Locate the retaining screw on the hub face of the rotor. Use the impact screwdriver in the reverse position with a Phillips head bit and strike the end of the screwdriver with the hammer. Remove the screw. Remove the rotor. If it is stubbornly stuck to the hub, strike it a few times with force on the plated fins of the rotor.
  6. Step 6 Spray the new rotor with brake clean and be generous to clean off the oil coating that new rotors have on them so they will not rust from condensation in the air while they were in storage. Clean both sides and wipe dry with a shop rag. Place the new rotor on the hub and make sure to line up the retaining screw hole in the rotor to the hub. Replace and tighten the retaining screw.
  7. Step 7 Replace the caliper anchor and bolts and tighten tightly. Replace the pads into the caliper anchor in the same manner you removed them. Replace the caliper over the pads and rotor and replace and tighten the caliper slide bolts. Replace the plastic covers.
  8. Step 8 Replace the wheel and lug nuts and tighten the lug nuts so they are flush. Lower the Mazda6 and torque the lug nuts alternately with the torque wrench, set at 80 foot-pounds and the 21-mm socket. If you raised both sides of the front axle, wait until you've replaced the right side rotor, otherwise repeat Step 2 through Step 8 for the right side.
  9. Step 9 Pump the foot brake pedal until it feels normal to restore the hydraulic pressure back to the compressed caliper pistons. Release the parking brake.
  10. Step 10 Check and add new DOT 3 brake fluid to the master cylinder and replace the cap securely. Close the hood. Remove the wheel chock and test drive

Calipers do not fully release


Make sure that the brake pedal has about 3/4" of free play before it actuates the master cylinder. Remove the front wheels and try to push the pads back into the caliper cylinders a little. This normally takes some effort. When pushed back, try to slide the caliper casting in and out as it normally floats to equalize the braking effort on both sides of the rotor. The pads depend on some lateral movement of the rotor turning to back off the pads as there are no springs to push them back. Make sure the pads are not worn to the extent that the little wear-warning tabs are touching the rotor. Hope this helps!

The right front brake drags and gets hot


When it drags, loosen the bleeder, if it releases, the hose is bad, if it does not release, the caliper is bad.

Replace front brake pads on dodge caravan 2006


Hi, here is the step by step guide you requested. its a easy read and it will help you with this replacement procedure.

Step1 Park the Caravan on a flat, level paved or concrete surface. Release the hood latch and apply the parking brake. Step2 Open the hood and **** out half of the brake fluidmag-glass_10x10.gif from the master cylinder reservoir using the turkey baster. Discard the fluid appropriately. Do not reuse it. Replace the cap on the master cylinder. Step3 Break the lug nuts loose on the left wheel first using the breaking bar and a socket. Do not remove the lug nuts or loosen them too much. Step4 Lift the Caravan using the floor jack and place the lift point under the transmission bushing. Place a jack stand under the inside of the rocker panel in the left front where the frame is boxed. Do not place the jack stand on the rocker panel as it will most likely collapse. You can leave the floor jack in place as an added safety support, but make sure to use a jack stand. Step5 Remove the lug nuts and wheel. Step6 Remove the caliper bolts with the ratchet and a socket. Gently pry the caliper off of the rotor using the screwdriver. The pads are clipped to the caliper. Step7 Remove the outboard pad first by prying it off the caliper housing with the screwdriver. Remove the inboard pad by pulling it out of the caliper piston bore. Support the caliper to the coil spring using the bungee cord. Step8 Compress the piston in using the C-clamp. Squeeze slowly and steadily to avoid damaging the caliper piston. Step9 Install the new pads starting with the inboard pad. Since the inboard and outboard pads are identifiably different, there's only one way they will fit properly. There is a slight difference in the molding of the backing plates of the pads. Refer to the old pads you removed to make sure you're applying the pads for the left side. Step10 Apply a liberal coat of silicone brake lubricant on the caliper anchor where the backing plate of the pads sit against. Step11 Reinstall the caliper over the rotor. Step12 Apply a light coat of silicone brake lubricant to the smooth area of the caliper bolts. Insert it into the caliper to lock it to the caliper anchor. Tighten the bolts properly. Step13 Replace the wheel and lug nuts, tightening the lug nuts as tight as you can using the ratchet and a socket. Lower the Caravan and retighten the lug nuts in an alternate fashion using the torque wrench set at 100 foot pounds and a socket. Step14 Repeat the procedure for the right side. Step15 Pump the foot brake pedal when you're finished with the right side until the hydraulic pressure is restored to the caliper pistons and the brake pedal feels normal. Release the parking brake. Step16 Check and adjust the brake fluid level in the master cylindermag-glass_10x10.gif reservoir. Only add new DOT-approved brake fluid for your Caravan. Step17 Remove the wheel chock and test drive.


Please rate and god bless:)
