The brake servo unit is faulty and must be replaced. Since this requires disconnecting the brake lines' it's very risky to do it at home so go to a repair shop.

How do I replace a brake booster on a 1998 Buick LeSabre? Brakes hold but make a whooshing when applied.


May not be the booster as some do make a noise when the brakes are applied. To test press the brakes several times with engine off, Press the pedal down hard and start the engine , the pedal should move down slightly and there should be no whooshing sound . if the above is ok so is the booster.

How to open brake fluid reservoir


You press down while opening. BUT if someone pressed down too hard last time, the reservoir might have slipped down in the clamp and now the clamp is jamming the lid from the underside. Check the clamp before applying much force.

When I stomp on my brakes let's say in an emergency the pedal is very hard and the brakes don't realy work at all but if I use them normally they are perfect it's on a ford au xr6 ute


to test your brake assist is working. stop the motor. Press w few times the brakes, till the pedal feels sturdy. Then while pressing the pedal down firmly, start the engine. When you feel the pedal going down, like feeling "soft" you know the brake assist works. If nothing changes it is defect.

HOW DO YOU BLEED THE BRAKES ON 100 SERIES CRUISER


Start the engine, fill up full the brake fluid reservoir, and let someone press the brake pedal down to the floor for 3 times,, bleed the bleeder screw behind the tire.. position yourself closed to back plate of drum or caliper for easy bleeding work. when the bleeding screws is loosed brake fluid leaks with a bubbles. then close it again and tell the guy in the pedal brake to press it again until a hard press is felt and bleed the bleeder screw again, stop only the process when there is a hard pressing already on the brake pedal which is the brake system is now working properly.

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.

94 Plymouth Voyager ABS light stays on


Had a similar problem a number of years back. Underneath the brake pedal arm is a small switch with a plunger. when you press the pedal down it moves the plunger in and engages the brake lights. when you let off it's supposed to pop back out (turning the lights back off). Possible it is getting stuck in the down position and could need to be replaced. very easy to install and only about an 8 dollar fix.
