I recently installed a Wilwood Tandem Master Cylinder (part number 261-13270) and an adjustable proportioning valve in my 1972 Chevelle. My car came with power disc up front and drum in the back. I got the brakes bled, bench bled the master multiple times but still could not get a good pedal. Ended up being the booster pin to master cylinder gap was out of adjustment.
Here is the tool I purchased on eBay from seller tomsclassic: bit.ly/3ctnc3G
I received no compensation to post this video.
Hopefully this saves someone the headache it caused me. Of course, make sure you have the proper bore size for your application, and make sure there are no leaks anywhere or air in the lines.

Great explanation. I had this problem on my '66 Nova, but the rod was adjusted too long, and my rear disc brakes were dragging and heating up. I made my own depth tool to fix it. Once the proper clearance was set, the dragging brakes went away. Opposite of your problem but just as annoying. Thanks

I've heard of that being a problem as well. I also think the constant pressure on the master cylinder isn't great.

I’m dealing with this right now on my 65 f100. All of my brake parts have been replaced. I was able to bleed the rear brakes just fine but nothing on the front brakes. A guy on an F100 forum suggested the same thing so I’m going to give it a shot tomorrow.

Hi, I converted my manual drum brakes to (YJ jeep) power disc brakes in my 76 cj7 jeep. I noticed the piston rod was slightly longer on the disc brakes than the drums. So lowered my pedal to allow the extra length. After converting to disc, I now I have soft brakes. I bled the system 4 plus times. Don't think there's air. But I didn't bench bleed the mc. And the pedal hardens up after I pump the brakes. I read I could adjust the piston rod in the booster. Any Idea On how to fix it? Thanks for the video.

Bench bleeding the MC would be the first step, you may still have air in there. The next step I would take would be to check the length of the pin and make sure that you aren't resting on the MC piston and depressing it slightly. If the pin is too long it will make it impossible to get all the air out of the system. Also, make sure that your engine is drawing enough vacuum for the booster with a vac gauge.

I wonder if the shaft is adjusted out to far if it would cause the Willwood to leak fluid. Mine Willwood is not even a year old and it leaked and killed my booster

Constant pressure on the MC piston is definitely bad. I’m sure it could cause the seal to fail.

Did the adjustment raise your peddle height?

@brendanmegannety7595 2 жыл бұрын

If it did, it was negligible. I only adjusted a few mm on the pin.

Your doing it upside down. The shot end goes to the master land the long end goes to the booster.

Thank you helped out a lot what an awesome video. Do you need that adjusting valve on the side of the master? Thank you

@brendanmegannety7595 Жыл бұрын

No, you can have a regular proportioning valve/combination valve. This is an adjustable proportioning valve to change the bias between front and rear brakes.
