SOURCE: 2005 f150 spongy brakes

it sounds like your still not getting all the air out of your lines. it helps to have a brake bleeder but they are expensive, it also could be that the gasket inside the master cylinder is inverted even if it is a new master cylinder this could be the case, ive had four bad remanned ones in a row, before i got a good one... hope i could help

SOURCE: Spongy brake pedal on 2003 Frod escort zx2.

loosen of the hand-brake adjustment and press the brake pedal a few times to self adjust the rear brakes.
Re-tighten the handbrake adj last.
Front brake sounds like a seized caliper,If possible remove caliper and clean and lubricate the piston.
This may work but replacement caliper may be the only other solution.Make sure the caliper slides are also clean and lubricated and the brake pads are in good order.(TRY THIS FIRST)
Also new brake shoes can make the pedal feel spongy for a couple of hundred miles until they have been run in.

SOURCE: Replaced brake pads on 2001

you need a new master cyclinder..you needed to open the brake line before you forced the caliper back in ,,,otherwise you force the fliud the wrong way though the master cylinder and ruin the internals

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn

Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

All of a sudden i have spongy brakes on my 92 f 250. changed master cyl and booster. and rubber brake hoses. still spongy and nothing is leaking.brakes went from being good to spongy in one...

Check the rear wheel cylinders? Was anything leaking at the master cylinder? Does it have ABS?
Check the front caliper slides are free. Check the front caliper pistons for leaks as well. This is all assuming you bled the brakes(all 4 wheels) properly after all that replacement! You're getting air from somewhere for sure or if it has ABS, the pump may have a problem.

Just replaced rear pads now it feels like i have air in the line, the pedal goes about 3/4 of the way down. i used a tool to turn the caliper piston in until it seated then put the pads on. now the abs...

that is how you contract the caliper on the Audi/VW rear brakes. I would check the brake fluid, I would also recheck the back brake lines as it is/was a bear to replace the rear brake pads. Hope this helped Tim

95 sierra k1500 low brake pedal and spongy have replaced master cylinder. calipers and rear wheel cylinders. bled brake several times. still the same

Sounds like you still have air in the system, you can get a brake bleeder with a one way check valve and put that in a bottle with a little brake fluid then when you pump the brakes it will allow fluid out without having to open and close the caliper fitting. just keep bleeding and I am sure you will get more air out. You might also try back bleeding where you pump brake fluid from the brake calipers to the master cylinder. Many shops do that now as it is more effective.

Brakes are still spongy after changing the pads, one caliper, and master cylinder. bled front brakes.

I just went to Brake Masters this morning and had them replace the Master Cylinder since I was experiencing the pedal very spongy and going to the floor. When they replaced the Master Cylinder and they gave me back the car, the brakes were still spongy and going to the floor. I addressed this to them and they took another look at it, but when I took it for a second time, the brakes were extremely spongy. It was almost like they gave me back my car in worst condition to when I brought it in. Can you help?

Changed caliper on 2005 ford freestar and now brakes are spongie.

Use a vacuum pump brake bleeder starting at the furthest point from the master cylinder. They cost abt $35. Be sure to keep master cylinder full... :)

I need to know how to bleed the brakes on a 1999 chevy blazer

Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.

Bleeding brakes

No need to run the engine. Start the bleed procedure from the caliper farthest from the master cylinder, and work toward it. This means bleed the passenger rear first, then the driver rear, then passenger front, then driver front. Don't stop bleeding any caliper until you get three or so consecutive streams of air-free fluid through the bleeder. Monitor the level of fluid in the cylinder, and be sure the cap is on while bleeding - only open it to add additional fluid as needed.
