Question Asked: vacuum loss during braking
July 15, 2009, 03:54 PM
I have had a spongy brake pedal and have a vacuum loss when I brake. I have replaced the master cylinder and bled the lines including the control module, 4WAL. I can still hear a squishing sound coming out the power booster boot. If I cover the end of the boot where the shaft comes out, I have a firmer pedal. Could that be my vacuum loss? Should I replace the power booster.

Sorry, Maybe I did not describe it properly. When I step on the brake it requires more effort to brake and I get a rough idle. Is this just the check valve or the brake booster failure?

When I press on the brake pedal the brakes are weak and I lose vacuum in the engine. Could this be the check valve on the power booster? Is this an easy repair? Thanks.
