Yes. The engine will idle poorly when a vacuum power brake booster goes bad. It can be a source of a large vacuum leak. A bad master cylinder however would have no effect on the performance of the engine.

The 92-96 Beretta/Corsica brake master cylinder is best removed with the ABS pumps and reservoir still attached. First, disconnect the 4 brake lines going to the top of the unit using a flare wrench. Now remove the 2 bolts securing the brake master cylinder to the brake booster. The whole assembly will come right out. Easy!


1990 Honda accord brake peddle sounds like air is in ther when pressed down?

Are you saying you hear a sucking sound when you push the brake pedal? If so, you may have a vacuum leak at the brake booster mounted behind the master cylinder. Check the hose going to the booster. The booster may also have a busted diaphragm and need replacing.

Remove brake lines going into master cylinder, properly dispose of all used brake fluid. Unbolt master clylinder from power booster. Remove pin holding break pedal (under dash on driver side) from master cylnder shaft. Install new part in reverse order of removing old part. Properly bleed master cylinder and brakes at each wheel! Ensure there are no leaks and you are done!


91 ford explorer brake go to the floor?

dont fully understand? if the brake pedal went to the floor there is a hole in the line some where or braking system If you are saying it is going straight to the floor like "whoosh" without any pressure then it is either your brake booster or master cylinder or both.


How do you know if the master cylinder is going out?

The brake pedal will sink to the floor when applied and the brake fluid reservoir remains full.


How do you replace a booster on a 1985 Chevy blazer S10?

I'm going to assume you mean the brake booster and not some turbo-charger that's been installed. -Disconnect and cap all the fluid lines going to the brake master cylinder. Remove the master cylinder. -Disconnect the hose(s) connected to the brake booster assembly. -In the cab lay down in the driver's side footwell and look up behind the brake pedal. You'll see 4 gold nuts somewhere right near where the pedal touches the firewall. Remove those nuts. -Back outside, gently wiggle the booster assembly until it comes off. The gasket can be sticky. There's a spring and a center pushrod on the backside of the unit so don't let those fall down into the engine bay. -Replacement is of course reversing these steps.


How do you replace power booster for a 1993 jaguar?

The XJ6 in this vintage does not have a standard, vacuum-powered power booster for the brake system. It is an electric/hydraulic hybrid system. The unit is located on the passenger side of the engine bay in the right corner closest to the passenger. Undo the brake lines and electric plug going to it and replace. Pretty strange, actually, the booster is almost always connected to the master cylinder, as in the older version of this same vehicle.
