Just got my car running, its a 90 Honda Civic DX Automatic.

I've been driving a 96 Cavalier with powerbrakes and when driving my car last night, The brakes didn't seem to do anything.

When I was pulling it out of it's spot, when switching gears it hit drive instead of reverse and even with my foot on the brake it jumped forward

Is there anything I can do, is there a way to put on powerbrakes?

 

Huh? Which vehicle are you talking about? What exactly do you mean by "power brakes"? Do you mean ABS or just vacuum assist braking? If its the latter, they come with those stock. If you are talking about the Honda - the master cylinders are known to fail.

 

Your Honda does have power brakes. The booster is the big black circular thing in the engine bay attached to the fire wall (brake fluid reservoir is attached to it).

- If your pedal is going squishy and goes too far down without stopping the car, you either have a fluid leak somewhere or you need a new master cylinder (internal leak past the piston).

- If your pedal is too rock hard for you to push enough to make the car stop, you most likely have a bad brake booster.

- It is also possible, however unlikely, that if someone has worked on the brakes right before this happened you may just need to re-bed the pads. I've seen this once on my friends Civic w/ Autozone pads. Every time we took the pads out and put them back in (in the same place) the brakes almost zero friction whatsoever. They required several hard stops before they would function again.

If your not sure about any of this, don't drive the car.

 

Well this was a problem before and we just bleed the breaklines replaced fluids ect, no leaks or air inside. But it still has an issue, Just replaced the engine as well. (Bad pistons)

 

Is the vacuum hose connected from the booster to the intake manifold?

Is the check valve in that hose working (you should only be able to blow through it one direction)?

Is the check valve installed the right way (air must flow from the booster to the manifold only)?
