Thread: check valve location

Tweet

I have to install some check valves in the brake lines as I'm having some problems due to the booster being located under the car.
Im making up a new brake line to come out of the booster ,it will come out the side of the booster and then head toward the front of the car ( 4 inch forward ) before I hook the brake line so it heads back toward the existing connect ( Towards the rear of the car.
Should the check valve be installed into the brake line heading toward the front of the car ( Same height as the booster outlet ) or should it be installed in the section after the hook which is 2 inch higher than the booster outlet ,or dos,nt it matter.

Thanks

You are talking about a residual valve. If the car has disc on the front and drums on the rear, you use a 2 lb valve for the front line. If it has drums all around you use a 10lb valve.
I have plumbed the 2lb valve in my lines right into the lines coming from the master cyl.
These residual valves help keep brake fluid from draining back to the master so the pedal stays firm.

The RESIDUAL VALVES can go anywhere in the brake line. I do not believe it matters but, I installed mine close to the master cylinder.

I have discs front and rear - and this is where my resid valves are installed. I didn't know a two sided fluid tap m/c was available until after I finished plumbing it.

Everything I've read, keep them as close to the master as possible.

thanks for the help
