brake pedal to the floor???

Hey everyone,

I noticed that when I have the AC on, my brake pedal goes to the floor, as if i am loosing brake oil or something. When I stop at a light, i feel I need to pump the pedal many times to get the car to stop.

the hand break is strong and the car brakes normal without the AC - WTF?

civic 96, si

thks for all your help in sheding some light on the issue -

Re: brake pedal to the floor???

i had a simmalar problem in my 4th gen. i ended up replacing the master cylender b/c it would leak and it would slowly sink to the floor w/o the a/c but with it would go down to the floor and just b4 it would hit it would stop the car.

replace the master cylender. worked for me

Re: brake pedal to the floor???

yeah at first i would say the master cylinder but it might also be something wrong with the power brake booster.

Re: brake pedal to the floor???

Brake booster... or simply a cracked vacume line. Considering it only happens when the AC is on.

Its probably a good time to replace all of your vacume lines any way.

Re: brake pedal to the floor???

+1 on the vac line. The brake booster works by making a vacuum between the pedal head and the master cylinder. Something is happening when the A/C is on to make the vacuum not work, probably a leaking hose somewhere. Get it fixed, I don't want my injury risk higher knowing that there are people knowingly driving on roads with bad brakes...
