Sounds like a leaking line...check the fluid level...if its low or empty you have a leek in the system.

    no leaks good fluid level. is it possible that the brain on the side of the master cylinder is bad, or booster or master cyclinder. not sure what to eliminate first. This happend all of a sudden.

    master cilinder....the brain on the side if for abs and can be disconnected...give that a try. if the booster was bad the pedal would be verry hard

Breaks go to the floor


Then you have a massive leak somewhere as the brake peddle should not go all the way to the floor without some low break fluid indication. I would check brakes at each wheel as something isn't right or your not seeing it. Have someone pump the pedal and look to see if after the wheel is removed that the brake actually tightens and loosens. Remember that 4 wheels means 4 brakes, but master brake cylinder (where you add brake fluid) could be bad.

Brake peddle is ok when car is not running.peddle goes to floor when engine is started


sounds like you need major break work. Check the pads, rotors and also the brake booster and master cylinder.

I was backing out of my lane way and I heard a clunk that came from the front left side. A few minutes later my break peddle when the floor and I needed to pump the peddle to stop. If I push down hard on...


Unless you have a leak in the brake system the only reason your brake fluid level master cylinder would be empty is that your brake pads are worn out. As they wear the fluid level goes down. You need to check for a leak at all 4 wheels and the complete system. If you find no leak then inspect all brake pads and replace as necessary. I would also bleed the brakes as you let the fluid get very low. More than likely a new set of brake pads will solve your problem. The only thing that is suspicious is the clunk you heard. Make sure a trusted mechanic gives your brake system a good inspection. It can be very dangerous if your brakes fail.

Just changed rear brake pads on 05 mazda 6. now


This is normal and you need to keep pumping the brakes till they reset there self. Once the brake peddle have reset there self and is firm, check the brake fluid level again and add brake fluid if low. After brakes have reset there self, go for a test drive around the block and check the parking brakes. Good luck.

I can't get back brakes on a 1995 Monte Carlo. I replaced the brake pads all around and put new line on the back. It had good brakes on the back when I started.


Have some one pump the break up and hold the peddle doun to the floor and take back break line loose and see if you are getting fluid to the back. if not you need to check lines for bends and clogs. And check the resivor for clogs and fluid. If you are then change the break cylinder It has gone bad.

After changing front rotors and brake pads on my 1999 Accord LX, Brake peddle goes to floor despite pumping them maney times. I do not have brakes.


You need to bleed them well..
Open the master cap.. Open the bleed valve on each break and let the fluid run out NOT letting the master empty all the way..
Run a few pints through and tighten everything up and you should be good to go..

Put new roders, brake pads, and calipers on 2002 Olds Alero. The brake peddle is really soft and goes almost all the way to the floor....Why is this? Car has 26,000 on it..


groan......master cylinder not brakes and rotors and what not. hopefully you kept all of you old stuff because there was probably nothing wrong with it. also, make sure that you do a realy good job bleading you break = air will cause the pedal to go down to the floor. also if you change the master cylinder, that you try and bleed most of the air out before you install it into your vehicle
