After replacing any part of the hydraulic system for the brakes, all air has to be removed. That you know. There are some vehicles that require a certain procedure to do so and, since you neglected to mention the make and model, I cannot direct you, give me the make and model and I will furnish you with the correct way to end your problem.

    If you are bleeding the brakes you have fo have pressure at the rear wheel. Because of the proportioning valve when the rear brakes are air bound the valve limits the fluid. It is best to use a power bleeder but if tha is not available the procedure is you bleed the wheels that are farthest from the master cylinder first. If there is no pressure to the back you have to take your time and keep bleeding until you get it. Blower brakes with the engine not running add to the difficulty but make sure the person on the pedal holds it until the valve is closed. I hope this helps.

SOURCE: no brakes after changing brake caliper & bleeding system

Sounds like you still have air in your brake lines. Make sure all your brake lines are tight. Then bleed again. Bleed the trouble side first, meaning right side, then go to front left, back left then back right, make sure that your brake fluid is also full

SOURCE: 1994 Toyota pickup front brakes don't release

Well I don't think you'll need to buy parts,it sounds like there may be sludge built up between the master cylinder and the proportional valve to the front brakes.Pull the valve off(follow the line off the master cylinder and you'll find the valve)clean it and then flush/bleed the master cylinder before you reinstall,Then flush/bleed the rest of the system.There's a relly good chance that may be all you need to do,but you may need to pull the calipers and clean them also.Comment back if you need more help,Good Luck(To)Yotaguy

Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

2000 Ford Taurus Wagon. Driver side rear caliper is not releasing fully. All pads and calipers were replaced at the same time. Notice diver side caliper sticking replaced and still sticks. Replaced brake...


I remember that each caliper is pushed back by "Rollout" after the brakes are pressed. If the caliper is harder to move it my not push back. May have to change O-ring seals on caliper.

Hope this helps.

good Luck

WHy dose my brake pedal push back and make a grinding noise


Look through the openings in your front wheels and look at the front rotors-are they gouged up? You are probably running metal-to-metal, pads to rotors.
Chances are real good your rotors will have to be replaced along with new pads, but if you catch it early enough you might be able to have them machined, although nowadays that is hardly easy to get done and the savings usually is not as significant as it once was.

Back brakes coming on before front on snow and skidding


the way the car brakes are on todays cars are. the front brakes a supposed to grab a second before back brakes. so I would look to see if fluid is ok! and check out the front brakes, you could have a sticking caliper, thats stuck in and not applying the front brakes properly. have a good day !! also when you check the brakes make sure the caliper slide pins are ok. if not the caliper will hang up. if they are sticking replace caliper pins and grease them up good so caliper slides on them. my 2000 malibu had a similar problem and I found that the pins on caliper were bad, replaced them and all is fine.

99 ram 3500 front brakes sticking, Replaced the front flex lines. Calipers don't seem to be sticking as I can push them back with a C clamp. I drove the truck after I replaced the hoses and it seemed fine....


First, make sure the pads aren't "frozen" to the caliper carrier. This is important, they must be free to slide. If the pads come out really hard, that may be your problem.
Most calipers have a small stainless steel clip that the pads seat into, and if rust gets behind these clips, it binds. I file them out and apply grease to keep rust out.

All new brake shoes on 97 jeep front callibers still sticking


The problem lays with the Caliper itself and/or the brake hose connected to the Caliper.
However if you replaced the pads, did you also replace the Rotors or have them Turned? The old pads wear the rotor. New pads on old rotors that have not been replaced or turned may end with rubbing or stuck brakes.
A simple way to test whether it's one and/or the other:
1. Remove the Caliper from the rotor, remove the pads. Keep for now the caliper attached to the brake hose.
2. Very slowly push on the brake, exposing more of the piston out of the bore. Not all the way. Usually until the rubber dust seal/boot is fully extended.
3. Check the seal/boot for cracks and tears, and if clean or not. Bad seals may prevent the piston from re-seating.
4. Using a c-clamp and pushing straight in: Try repushing the Caliper Piston back into the Caliper Bore (the cup back into the hole). It should go back in realitively easy.
5. If it doesn't go back in easy: Again slowly pump the brake and re-push the pistons back out to full extended seal/boot (but not the piston out of the bore).
6. Detached the brake hose from the caliper.
7. Again using a c-clamp and pushing straight in: Try again to repush the caliper piston back into the bore without the hose attached. If it goes back-in relatively easy - the caliper is okay...it is the brake hose.
8. If the caliper piston does not go back in easily - Replace the caliper.
9. When Installing the new (reman) caliper, remember to bleed the brakes.
TRY EITHER OR #10 OR #11 BELOW:
After the new Caliper is reattached to hose and has been bled:
10. Again push on the brake petal to fully extend the caliper piston fully (rubber seal/boot fully extended) Again do not push the piston out of the bore! Try pushing the piston back into the bore. If it does not re-seat relatively easy: Replace the brake hose.
11. Another method: After replacing the new caliper back on the rotor: Assumng the entire front end (2WD front wheel drive) or entire vehicle (2WD rear wheel drive) or (4WD all the time) is jacked up off the ground
a. Put the lug nuts back on the rotor.
b. Have helper Start the vehicle and place in Drive. Don't step on gas!
c. Have then let off the brake and then engage the brake.
d. When they let off the brake watch to see if the Rotor is turning or not, if rubbing or not. Or if still sticking.
e. With a new caliper, turned or new rotors, and still a problem? It is the brake hose!
12. Replace the brake hose and try again.

Another method but more expensive:
OR Replace the calipers, brake hoses; bleed and test!

93 beretta front passenger brakes dragging caliber is locking up abs lights on not sure what else to do already changed caliber and pads still doing the same thing


If the same caliper is sticking,the replace the brake hose,it has colasped on the inside.Pushing the pedal down will force the brake hydraulics threw the brake hose,but the colasped hose will not allow the fluid to return,therefore holding the caliper from returning to it`s idle place

Abs brakes


The most over looked culpret and is also a good possibility could be a brake hose that is deteriating on the inside of the hose or frozen or un-lubricated slide pins. Not just any old grease will do. You you need caliper grease for the pins. The grease has to be able to withstand the heat and not break down. You don't want to go overboard with the grease either because it will collect brake dust and gum up. A light coat is great. If the caliper is able to be compressed back into the caliper with the bleeder valve broken loose then it's likely you have a bad hose. Replace hose and bleed brake system starting from the right rear brake, then left Rear, right front and finally left front. If it doesn't back off check the slide pins for ware and that they function and are not frozen up. Do you see any wet fluid leaking from the caliper or on the brake pads and rotor? I have a 1 ton Ford Diesel that the Rt Front caliper wasn't backing off until I broke free the bleeder valve and found that it was not the caliper, but the hose was bad, the slide path was all rusted and the slide pins were shot. Replaced for hose, slide pins, wire brushed slide path, and greased slide pins and path with caliper grease. Bought a small bottle of brake fluid to bleed the brakes. Total caost was aprox $25.00. New caliper for my truck would cost me $64.00 plus core charge for the old caliper. I had to change out my calipers in the rear as well so that's how I know the cost saved. If you have those little shiney clips that the pads ride on (top and bottom) you need to pop them off and knock loose any rust, brake dust and dirt and then clean up the clips with a wire brush. What happens is rust (usually) bubbles up under the clip and makes the clip raise up slightly. You can't really see the clip raised up but the tolerance is so close that the pads will actually bind up on the bubble and make it seem like the caliper isn't releasing. Depends on what style you have.
