Likely a slipping belt. Accelerator makes the engine spin faster, which can let the belt slip more. There's a spray product called "belt dressing" that might stop the slipping temporarily - at least long enough to see if that's the problem. Or, you might be able to inspect the belts - with the engine off - and see if one is noticeably loose.

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. ^^

Gas peddle won't produce rpm's. kind of a rough idle. Vehicle will move when put into gear and brake released but pressing gas does nothing.. (automatic)


did you check and see if the cable snapped for the accelerator, have someone push the peddle a few times and you watch to see if the accelerator lever that the cables connect to move if not they obviously broke and need to be replaced

When push brakes you have to push really hard to make them go in then the truck barely stops. Replaced the MC and bled the brakes now every time push brakes truck acts like its going to die. Brake light...


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.

There is an air leak under the dash and it ties in with the brake pedal


It is a defective brake booster. When the internal diaphram of the brake booster develops cracks or pinholes from age, the crankcase vacume pulls air through the defective break booster diaphram from the air intake valve located on the rod connected to the brake peddle. At first the air leak sound my change or even go away when the brake peddle is depressed. But over time the booster diaphram will detierorieate to the point where the air leak sound will be contiuious. This is a problem that should be addressed ASAP as a defective break booster reduces the power assist to the break peddle and may make it difficult to apply enough break pressure to stop in an emergency situation.
Have the brakes checked by a certfied brake shop right away.

94 s10 chevy 2wd brake pedal fades to floor before stoping


Might check around the big black round muffin shaped chamber adjacent to the master cylinder for a loose vacuum hose or crack therin; the hissing sound seems likely to be the air rushing in as you loose the vacuum that supplies the power to assist your braking effort (power brakes)---as this goes, so goes your peddle until it reaches the actual piston pushing the brake fluid (which should be firm like with non-power brakes).
...maybe have an assistant push on the peddle while you listen with a piece of hose or a stethescope to find the leak (or I suppose the power unit diaphragm could be shot/leaking--hence replacement), but since you said after bumpy road etc, one could hope for a simple dislodged vacuum hose or fixable crack.

Loud screeching noise coming from car after stops.


the screeching noise is most likely caused by a slipping belt or pully. transmission probably needs fluid and filter changed.

My 1998 ford ranger 2x2 has shown to accelerate upon braking


This sounds like your rear brakes are out of adjustment and the brake peddle has too much travel. On a sudden fast stop both the brake an gas peddle get stepped on. Had this prob with a car last week. Frankster016
