4 wheel disc brake line plumbing

Recommended Posts

Hi, All

I'm doing a 4 wheel disc brake conversion on my 70 Monte Carlo and have a  question.

 

Do I need to use a front and rear hold-off valves? 

I know that I need a proportioning valve,. Right now I'm just running the brake lines on the chassis as the body is off of the frame.

Is there anything else I'm missing?

If by hold down valve you mean residual pressure valve, no, none are used with disc brakes.

Thanks Paul,

The Monte had one (valve) at the rear of the frame one the driver side. The car had front disc brakes from the factory. I didn't think that it would be needed.

Thanks again,

Bob

Bob, can you post a pic of this valve?

I've never known them to be mounted on the rear frame, they're usually under the master cylinder.

The separate hold off valve is only on 1970 cars.
