There are several things that you need to do to get a good pedal. Start bleeding the brakes on the right rear then left rear then right front then left front. also when bleeding the brakes DON'T PUMP THE PEDAL Push it down once to keep from mixing the air with the fluid. Then let off of the pedal and wait 5 seconds before pumping once again. This takes longer but it is effective. Make sure you have new fluid going through the system at the right rear before going to the next wheel.
Air in the brake system- Brake system needs to be bleed and fluid needs to be added while you are doing that.
Usually means they probably didn't bleed the brakes or did not top off the brake fluid
If You Replaced the master cylinder Did you Bleed it as well? if not you need to bleed it first. then bleed the brakes start with the passenger side rear, then driver side rear, then passenger side front, then finally the driver side front.
Bleed the brake lines and make sure there is no air in the system.
Try bleeding your brakes. If there is air in the system it can give a spongy feeling to your brake pedal and require you to pump your brakes and/or put your brake pedal to the floor.
try and bleed brakes , if that wont work you need a master cylander
It sounds like you need to bleed the system of air.
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.
Defective Master Cylinder or broken brake line. Replace the master cylinder and bleed the brakes.
you either need to bleed your brakes, add fluid or get a master cylinder email@example.com
bleed your lines,may be air in them
you need to have some one in the car to pump the brakes till thay get hard. and win they do you crake the bleder open on the brake calaper.the brake will go to the floor then you titan the bleder. and repeat thia over till the brake flouid comes out and there is no more air in the line.
To bleed the brakes on a 1995 Sonoma, start with the back passenger side wheel and loosen the bleeder screw. Have someone pump the brake three times and hold the brake pedal to the floor. Tighten the screw. Repeat this procedure for the other three wheels moving in a clockwise circle. A wheel may have to be repeated. Continue until only brake fluid comes out of the bleeder screw.
If your brakes are making a squeaking or a grinding noise when you are coming to a stop this is usually an indicator that your brake pads need to be replaced. Also, another sign that your brakes need to be replaced would be if your brake pedal goes all the way to the floor when pressed and it seems to be taking longer to stop.
Brake Pedal Goes to the Floor After BleedingAlthough there could be more than one reason, I suspect that even though you may have bled the brake system, AND the brake fluid reservoir is full, your brake bleeding was not successful, and you STILL HAVE AIR IN THE BRAKE LINES, or in the wheel brake slave cylinders.
I had a similar problem and it turn out to be the ABS valve located on the frame rail on the front driver side of the vehicle.
You have to pump the brakes a few times after changing brake pads to take up the extra space until the pad touches the rotor. In extreme cases, you may have gotten air in the system and need to bleed the brakes. Make sure the reservoir stays full of brake fluid as you pump the brake pedal.
The master cylinder MUST be bleed first before any bleeding at the wheels can occur. if you do not do this, you will be bleeding for hours.
To bleed the brakes on a 2002 impala, have a helper pump the brake pedal then hold it down. Open the bleeder valve at one wheel, and let air and fluid flow until the pedal goes to the floor. Close the valve and repeat. When there is no air in the fluid, then move to the next wheel and repeat.
Not really an answer, but another question... did you bleed the brakes after you changed them? I remember that is a critical step, NOT to be missed when working on the brakes. Hope this helps.
To bleed the brakes in a 1993 Toyota Camry, open the bleeder screw on the rear passenger side wheel. Have another person pump the brakes 3 times and then hold the pedal to the floor. Tighten the bleeder screw. Continue with each wheel until only brake fluid comes out and not air when the brake is pumped. The next wheel should be the driver's side rear and then the passenger side front, then driver's side front.
replace the master cylinder it is probably worse when temp outside is hotter i just replaced mine on a Honda was doing same thing works perfect now..make sure you bench bleed the new m/c before bleeding brakes
First, make sure the master cylinder is filled with brake fluid. If it is low, there may be a leak somewhere in the brake lines or a brake cylinder. If the master cylinder is bad, you can normally pump the brakes up, but the pedal will slowly sink to the floor again. The master cylinder needs to be replaced or repaired.
== == Sounds like you have a leak somewhere in your brake system. Fill the master cylinder with brake fluid and bleed off all four calipers. Once you have brakes again check the system for leaks at the calipers, master cylinder and along the brake lines.
