Brakes won’t bleed

Burnsy01 · Mar 31, 2018

What’s up guys . I cannot for my life get my brakes to bleed on my 68 camaro. Manual disk/drum setup. Master is from a 72 nova. I’ve tried 3 masters and nothing . The proportioning valve is brand new and I can’t find a exact diagram to if I plumbed the lines right . Any help is extremely appreciated .Thanks, Nick

You didnt happen to change the front calipers did you? I put mine on backwards once (bleeders down) and thought I was loosing my mind why the brakes wouldn't bleed.

I think you have something wrong with the routing. After looking at the pictures, you should have two front lines that connect to the left and right sides of the proportining valve, Then the line from the front of the master should go to the front of the proporting valve.

The set up I described would be for a drum/drum set up. Since you put front disc on, you should have a proportioning valve plumbed in. The proportioning valve I described in my other post is actually the distribution block.

From the picture of your calipers it appears they are on backwards. The bleeders need to be on top, not the bottom. Swap sides (put the left on the right and right on the left) and that will put the bleeders on top.

If he wants to keep it stock looking, he will need a seperate proportioning valve. The photo above is a combination valve. I used a combo valve on my 69 for years. I believe it came from a 70 Monte Carlo.

Although a combo valve, I'm pretty sure the lines go the same way.

Alright fellas , the calipers were flipped .Thanks you guys for all the help! The pressure is amazing

You might want to take a look at your rag joint.

The stock proportioning valve, if so equipped, was located on the subframe, The disc brake valve under the MC is a metering/hold off valve.
