You did something wrong. -Go back over all steps carefully (preferably with manual) and see where you went wrong.
Yes, replace the brake booster and master cylinder.Yes, replace the brake booster and master cylinder.
Yes, replacing the booster is fairly easy. Just remember to bleed the brakes if you have to remove a brake hydraulic line. Bleed in this sequence. RR-LR-RF-LF
There was no Caprice in 2004...
the rear is usually smaller and closer to the brake booster
1)Look for a wet spot where the master cylinder connects to the brake booster. In most cars, this is where the the brake fluid usually leaks. The brake fluid will eat away the paint on the brake booster. If it is wet here, the master cylinder needs replacing. When the master cylinder is removed, you'll see that it is wet (should be dry) where it was connected to the booster. 2)Check all 4 brakes and look for wet spots on the calipers & wheel cylinders. Same things apply here. Replacement might be needed. 3)Check where the brake hoses/lines connect to the brakes.
Bleed the master cylinder.& then rebleed the system.
How to fix brake will not bleed out
The brake booster is what gives you power brakes. In the engine compartment in front of the steering wheel is a round black flat ball looking thing. That's the brake booster with the brake master cylinder attached in front of it. The brake booster uses VACCUM from the engine to multiply the force that your foot applies to the master cylinder. Used with power brake applications
I'm replacing the brake booster on a 2000 kia sephia and how do you ajust both rods on the brake booster?
No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.
Did you bench bleed the master ? Are the calipers and wheel cylinders working properly ? Is there a break in the line somewhere ? Last , is the booster working properly ? What happens when you step on the brake now ? Are they soft and spongy ? Does the car stop at all ? More info is needed to answer this question properly.
There is a gasket between the master cylinder and the booster of a 1990 Acura Integra. It is shaped like the side of the master cylinder with two bolt holes.
