Start at a point when it worked perfect. I find on this web site and with vehicles people don't give specific info and who does all the troubleshooting? The owner or a professional repair shop. Brakes do not catch. They can go to the floor but you would never leave the driveway in that state. So who bleed the brakes, how was it done. Was this just scheduled fluid flush you should do every two years or was it after replacing a hose.brake line caliper ,where the system was opened? What other repairs have been done in the past year even though they may seen unrelated. Work with me here and I will help you

Sounds like a master cylinder failure. also did you check all the caliper slides?a stuck caliper slide could also cause this.

have you replaced something on the brake system? because unless the brake line were opened up air cannot get in there so bleeding usually don't help because if air is introduced into the system by opening a line somewhere the air don't get in.

a stuck caliper slide could create this problem and a master cylinder is the most common.

if you have any more question please ask i would be glad to help.

good luck

If there are no external leaks the master cylinder is probably the problem

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.

Brake lines all hooked up bled lines 4 times still brakes go to floor almost. But if pump them they come back up sorta. But the when drive , they go back down any suggestions


You could possibly have a leak somewhere or the break booster could be bad. I'd check for all leaks first. Only way I know to check a brake booster is to change it.

Break goes to floor before it stops !


If you can pump on the brake, and get brake to not be so far down, then you possibly have air in your brake lines. Get them 'bled', which is removing the air, and you may be OK...not too expensive...

Brake pedal goes all the way to the floor, will slow the car a little, but wont fully brake. master cylinder is fine, calipers and pads are new, brake lines look okay, it's holding brake fluid fine, lines...


must be something you have overlooked. clamp off the front brake hoses and rear hose. if you dont have the propper clamps use g clamps or locking pliars. try the pedal then. if it still goes to the floor its either air in the lines or the master cylinder is no good..Bleed the master cylinder at the lines first,then work back.

We just replaced all the brake lines on our 2000 Concord. We bled the brakes, but still don't have great brakes. Is there steps we needed to take when we bred the brakes. The brake light is also...


When bleeding a break system have one person pump the breaks around 10 times and hold the pressure to the break peddle while the other person loosens the bleed screw......The peddle will then go to the floor..............Hold to the floor until the bleed screw is tightened again and repeat until no air is in the line............Repeat for all breaks and always check the master cylinder for low fluid level and top up.................Hope this helps you out.

Either you didn't bled it thoroughly or the line isn't correctly installed and it leaks. Check everything again and do a proper bleed this time.

Brakes don't kick in till the almost hit the floor board


The first thing that i would investigate is when the last time that car had a brake job, if the pads are good on the car and the pedal still seems to be extra soft, you (A) either have air in one of your brake lines causing the soft pedal, or (B) you have an air leak in one of the brake lines, an easy indicator is to see if there is any brake fluid on the ground under your car, if not, i would start checking for oily residue on the master cylinder, then follow the brake lines to the wheels of the car, looking for any signs of leaks or damage.

Hope this info serves you well

Keep getting air in break lines


1. bleed your vehicle while the engine is running. 2. Check ALL your brake lines, connections and wheel brakes cylinders or calipers of any leaks or moisture. 3. If nothing happens, your brake masters or your caliper's pistons may be weak and needs replacement.
