Check vacuum hose from engine intake manifold to booster behind brake master cylinder. Check for leak or cracks in hose. If brittle, replace hose.

SOURCE: spongy brakes

I have had the parts stores give me the wrong pads for these before but also these have a little *** or bump on the back of the pad. this bump has to be in the right position or it can cause the caliper/piston not to seat properly. you may have to disassemble and look carefully for this problem. sometimes the caliper won't sit flat on the pad on the outside because of that little ***. also it can be under the piston. just get rid of the *** if you see it and reassemble. make sure you bleed from all the bleeders not at the closest line that comes free.

SOURCE: I want to puul fuse

these use by directional braking like the volvos have used for decades.that is the left rear brake works with the right front brake and right rear brake works with the left front brake.this is how the brake lines are connected to work for the braking system.so when you have a brake leak you will have to bleed the opposite brake to get the air out.this maybe your problem also if the abs system has air in it then it will have to be bleed of air.

There is a running pump sound when I put on brakes and sometimes when I don't hit brakes and a grind sound


Shelly, in most cases, these can be cured by replacing your brake pads/shoes. However, you stated that you are hearing a "pump" sound when you depress the brake peddle. So this is telling me that you may have either a vacuum issue, or having an issue with your "Brake Booster". That also runs off a vacuum. A little info for you. ^^ When your engine is running, the entire system is put under a negative vacuum. This controls things like cruise control, and vacuum assisted brakes. Older vehicle did NOT have a vacuum assist, and were called "Manuel Brake" systems. While these were more reliable, the were harder to push the peddle until the brakes worked. As an example, with your car turned off, depress your brake peddle about 3 times and then try to press it as if you were stopping. You will find that the peddle is much harder to press than if the engine were running under the vacuum. The reason I asked that you depress the peddle 3 times, is when the engine is off, you are no longer building pressure, so this pressure is naturally bled off when you use the brakes. If this does not happen, and your brakes are always hard to depress, then for sure your having a problem with your brake booster. I hope this helps, and good luck. ^^

Your bake booster has failed causing a massive vaccume leak when you apply the brakes. That in turn gives more air to the system so the computer tells it to add more fuel thus causing the rpms to go up. Replace it %99.5 chance that will fix it.

The brake peddle is very hard to push, it's like there is no booster? The peddle is not spunge at all, it's hard as a rock and I am a 275 lbs guy and it's difficult for me to get it to stop?


Check if there is any difference in the feel of the pedal when the engine is running or the engine is stationary. If the feel and required pressure is the same, the booster is not working. Check the vacuum lines for cracks and leaks. If these are intact, the booster diaphragm might be leaking and the booster needs to be repaired or replaced. If there is a slight difference in feel, try replacing the brake fluid - empty the reservoir and refill it with fresh fluid and then bleed the brakes until new fluid is seen coming out of each bleed point. Remember to top up the reservoir regularly to prevent air getting into the system.

The parking brake peddle dow not set or engage. Everything is connected and working just won't set. Extemely hard to push. what do I do? thanks


Sounds like rusted cables. you can try some penetrating fluid at the rear brakes on teh cables, but most likely you will need to replace the whole cable system if it's too far gone.

Sounds like you will have to bleed your brakes again, but thats not the problem og hard brake peddle, need to check your power brake booster, sit right in back of master cylinder, check make sure it has vacum going to it, also to test it with engine off, press on brake peddle three time, then state engine with foot on peddle, peddle should go down a few inches, also with engine of peddle should feel soft for three pumps, if you have none of this , power brake booster is bad.

thanks for the good information

the air sound AND the hard pedal means you have a brake booster concern

if the car is running ok we can rule out vacuum leaks so that leaves the check valve but with the car running even a check valve wont cause the concern

therefore you need to replace your booster

semi-tough job because you have to remove the master cylinder and typically there may be some push rod adjustments afterward

depending on your level of experience you may want to seek professional assistance
