You need to bleed the system of air--make sure the master cylinder is full. Have someone rapidly pump the pedal several times until resistance is felt, then hold the pedal down while you go to the rear passenger corner wheel and loosen the bleed valve until the pedal sinks to the floor, then re-tighten the valve. Again pump the pedal several times until there is resistance and hold. Loosen the bleed valve again until the pedal is to the floor. Repeat this until the fluid coming out doesn't 'spit' air bubbles. At this point, move to the driver side rear wheel, then to the passenger front, and finally to drivers front. At this point, you should have firm brake pedal action. Be very sure to check fluid level in the master cylinder and top off each time you bleed. If done commercially, they pressurize the master cylinder with extra fluid from a special tank and cylinder adapter, then bleed each wheel in turn--much faster. Hope this helps!

Got an '03 Chevy Cav Sdn, new front pad,changed hydraulic line. Now brakes stay engaged! Can bleed off pressure thru bleeder, will not return fluid to master cylinder.Bled green fluid!Help!


It certainly sounds like the brake hoses are kinked or collapsed internally. Did you replace the flexible hoses or the steel hydraulic line? When you removed the calipers to change the pads did you let the calipers hang by the hoses or did you support them? When reinstalling the calipers did you make sure the hose wasn't twisted or kinked? The fluid certainly shouldn't be green, are you sure you're bleeding the correct thing?

What is next? Brake pressure is non-existent on all but front left. Pedal pressure is very hard. Replaced all calipers and master cylinder. Fluid does not exit nipple when bled on all but left front.


Its possible that your rubber lines are collapsed. I've had them keep fluid from going thru as well as not releasing pressure. See if fluid gets to caliper thru rubber. You can plug it with your finger and release pedal. If you feel vacuum and fluid flows well when you push brake, that's probably not the problem. Its somewhere to start tho.

Mazda drifter 2.5 diesel pulls left when brakeing


it could be that the right side caliper is stuck in the open condition. there is something blocking the brake fluid to the caliper or the piston is defective and is stopped mechanicly. jack up and block truck remove front tires, with a helper have them push on the brakes while you observe the calipers if the left piston moves and the right doesn't then you have found the problem. now trouble shoot unscrew the bleeder valve and have assistant push on the brakes. If fluid comes out then it is the caliper. If no fluid then work your way back toward the master cylinder at every connection. sometimes the rubber hoses that go to the caliper rot from the inside out causing a no fluid getting thru problem. hope this helps

Disk brakes are automatically self adjusting. If you have too much travel in the pedal, bleed the brakes. Let us know if you need the procedure.

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.

    1999 tahoe.right front brake caliper slow to release.


    Besides changing the caliper did you by chance chg. the break hose going to it, there a 2-way hose fluid goes to caliper and returns thru same hose, and they have been known to cause what you have just discribed.

    Brakes slightly engage after about 10 minutes


    well from reading of your problem, i am going to say its the calipers again, witch it could very well be, but there is something else it could be, There is a rubber break hoses that come from the hard line to caliper, there like a two way street fluid runs to caliper and back thru same hose, if there is a restriction or if it got kinked at one time it won't let fluid run back to resavor hence breaks don't release all the way and rub rotors and wear out pads. now calipers will do same thing. most of the time if there used and you squees the piston back in, when they come back out, like when you step on the break they will stick and not release or at least all the way and wear pads out prematurly. so my advise to you is this, new break hoses, new calipers and i think it will fix your problem. Hope this will help. OLD.SCHOOL.
