The master cyl must be filled and bled before install.after installing new bled master cyl,bleed all calipers.once you are sure there is no air left in system then you will need a scan tool to perform a abs service bleed.if you do perform the abs service bleed with a scan tool the brake pedal will be soft and start to fade.

Soft pedal on 03 grand caravan


Have you driven it since the brakes where replaced?

Did you bleed all four wheels?

have you "broken in" the new pads?

Are the rears drum or disk? If drum are they adjusted correctly?

are you using remanufactured master cylinders? If so keep replacing them. eventually you will get one that works. New is pricey but a better way to go.

Toyota surf brake problem


If you replace the wheel cylinders or brake calipers and did not bleed them properly, you most likely have air in the lines, If the rear brakes are drum brakes they need to be adjusted (if taken apart or new parts put on) or the pedal may sink when pressed.
1. If the brake pedal is soft when pressed down, the brake lines have air in them and need bleeding to remove the air.
2. a soft brake pedal can also be a bad master cylinder. Replace the master cylinder if the lines have been bleed correctly but the pedal is still soft or sinking when the pedal is pressed.

Just replaced rotors, calipers, caliper brackets, and pads. Bled all four wheels, starting with the farthest away from the master cylinder working my way to the closest. Brake pedal feels firm when car...


Bleed with the car running and make sure all the air is out. Now make sure there is no leak and the pad contact are adjusted without much gap so that the calipers hold on. make sure the servo assist is correct, if so and the master cylinder was set right , it must work. Please recheck all your work once again to trim up.

1996 Suburban. Does the brake pedal gradually go all the way to the floor if the problem was worn brake pads ????


no worn pads do not cause a sinking pedal, you have a defective brake master cylinder, the seals inside the master cylinder are leaking

Having trouble bleeding brakes on 1997 olds bravada. bled all four still pedal goes to floor. any suggestions?


Are the rotors worn? Worn rotors and new pads will sometimes cause this. The pad sits across the ridges and no matter how much you bleed the system the pedal just wont stiffen up. (See diagram. A - New pads, B - Rotor, C - Ridge)
If you did not install new pads you may also want to check the master cylinder seals. First bleed the system at the pipes that connect to the master. If the rotors are ok, you've bled the master cylinder and the problem persists then replace the seals or the complete master cylinder.

Need help changing brake pads and routers on 2003


Remove brake fluid from the master cylinder brake fluid reservoir until the reservoir is approximately 1/2 full. Discard the removed fluid.
  1. Raise and safely support the front of the vehicle. Remove the front wheels.
    1. Remove or disconnect the following:
    2. Front brake caliper guide pin bolts
    • Brake caliper by slowly sliding it up and off the adapter and brake rotor. Support the caliper out of the way with a strong piece of wire. Do not let the caliper hang by the brake hose or damage to the brake hose will result.
    1. If necessary, compress the caliper piston into the bore using a C-clamp. Insert a suitable piece of wood between the C-clamp and caliper piston to protect the piston.
    2. Outboard disc brake pad from the caliper by prying the brake pad retaining clip over the raised area on the caliper. Slide the brake pad down and off the caliper.
    • Inboard disc brake pad from the caliper by pulling the brake pad away from the caliper piston until the retaining clip on the pad is free from the caliper piston cavity
  • To install:
    1. Be sure the caliper piston has been completely retracted into the piston bore of the caliper assembly. This is required when installing the brake caliper equipped with new brake pads.
    2. If equipped, remove the protective paper from the noise suppression gaskets on the new disc brake pads.
    3. Install or connect the following:
      • New inboard disc brake pad into the caliper piston by pressing the pad firmly into the cavity of the caliper piston. Be sure the new inboard brake pad is seated squarely against the face of the brake caliper piston.
      • Outboard disc brake pad by sliding it onto the caliper assembly
      • Brake caliper assembly over the brake rotor and onto the steering knuckle adapter
      • Caliper guide pin bolts and torque to: 35 ft. lbs. (47 Nm) on 2002–04 models or 26 ft. lbs. (35 Nm) on 2005 models
      • Front. Apply the brake pedal several times until a firm pedal is obtained.
    4. Check the fluid level in the master cylinder and add fluid as necessary. Road-test the vehicle.

    For the rotors:

    1. Remove brake fluid from the master cylinder brake fluid reservoir until the reservoir is approximately 1/2 full. Discard the removed fluid.
    2. Raise and safely support the front of the vehicle. Remove the front wheels.

    I just replaced my front rotors, pads, and calipers on a 98 olds achieva. After doing this I bled the the front brakes but am now experiencing a very soft pedal. I am wondering if something else could be...


    Because of the ABS system if you press the brake pedal with too much pressure then it will give you the illusion of a soft pedal. Does it feel like a soft pedal when the vehical is in motion and you then press on the brake pedal (normal)? The other thing is if your pads and/or caliper were frozen, when you changed them out. The brakes are not going to feel or brake exactly the same, after the repair. But you are there, if the pedal is real low or goes to the floor then there is still air in the system or for some reason, your master cylinder is defective.

    Soft brake pedal after rotor replacement


    If they rebled the brakes and the pedal goes to the floor, chances are that the master cylinder is bad. Probably cost about $80-100 for the part if you could do it yourself

    My brakes are locking up on all four wheels on my 04 sentra.


    Your brake light switch is adjusted in all the way and is pressing on the brake pedal. This causes the brake to be slightly applied. As you drive the vehicle the brake fluid heats up and expands, the brakes will apply more and more until you see the smoke. Bottom line: your brakes are always applied at the master cylinder because something(usually the brake light switch) is out of adjustment.
