Spongy brake pedal even after ABS bleed and base brake bleed.

The brake pedal in my 2001 Chevy Venture was hitting the floor when I tried to brake.

Changed the master cylinder, changed the calipers, changed the wheel cylinders. Got it bled at a GM Goodwrench garage because I know that you need to have an ABS scan tool purge the ABS module.

I got it back and it was still a little spongy. I thought it was cause my brakes were low, so I changed the front pads and rotors. The brakes are STILL spongy. With the ABS module bled and no sign of bubbles in the brake system, what else could it make my brakes still spongy?

Thanks ahead of time.

Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.

If you had the system bled out at a GM dealer ship the car should been road tested before it left, checked for proper operation.
I'd check to make shure that all calipers/ wheel cylinders are working. If there is a non working part then your system is not fully operating, only using part of the system. You can check this by lifting the car and turn the wheel and have someone step on the brake if you can't turn the wheel ok, if you can still turn it i'd be looking for a siezed cylinder or a malfunction caliper or cailiper slide. Good luck

If the brakes are spongy, there is still air in the lines. Are you sure that you are using the correct technique to bleed the brakes as it is generally a very simple job to get all the air out.

2001 chevy venture van the brake pedal is soft and it goes down to the floor is it the m/c or the abs unit

The symptom you have is caused by a defective Master cylinder. Bench bleed the master before installing to keep air out of the ABS hydraulic control unit, if air gets in the unit the car will need to bleed of air using a special tool at the dealer. Do not get brake fluid on any painted surfaces or in your eyes, use proper safety gear. Only use special tubing Flare nut wrenches on the brake line fittings or you will round them off. Making up new lines is a whole other thing that requires special skills and tools.

Check your parking brake. if it goes down to the floor or does not hold, then your back brakes needs adjusted. bad master cylinders bleed off slowly to the floor while pushing on the brake pedal. If you need assistance on adjusting let me know.

Spongy brake pedal

I have a 2001 Chevy 1500 4 X 4 that recently had all new pads, rotors, and calipers installed. Since then my brake pedal goes almost to the floor before I get any brakes. I took it back to the shop and they bled the brakes with no better results. I bled them also with no results. I took the truck back and they installed a master cylinder with no results. It's now at the Chevy dealer and they say it's normal - BS! I had good brakes before I had all of the brake parts replaced, no one can figure it out. If you have a load in the truck or if you tow anything you better be looking at the ditch to avoid an accident. The original brakes would put you nose into the windshield and now I could stop it better the Fred Flinstone way. Anyone have an answer????????

Spongy brakes

Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.

Brakes feel spongy.when pressed hard goes nearly to floor.if pedal released slightly and pressed again feels normal.this is a 1997 toyota caldina GGT with abs.have bled brakes and sgimmed discs.any ideas?

Either you did not bleed the brakes properly or they need adjusted. (rear only) Front most likely are disks. If you put pads on the front and spread the caliper pistons, you should pump the brake pedal 10 or 15 times to move the pistons out. Some ABS systems are notoriously hard to bleed.
