Thread: Brake Booster Problems

G'day guys

Have just had a problem with the series 3 pop up in the last week or so. The booster on the brake system seems to have gradually stopped working. When I apply the brakes the the pedal seems heavy, but after a second or two the booster seems to kick in and start working, gradually increasing the braking effectiveness. The Vac pump is fairly new and is producing normal vacuum, I have also checked to see if the vac hose has collapsed but cannot find anything. Anybody have any ideas?

Cheers
Paul
