JBugs - 1971 VW Super Beetle - Dual Circuit Master Cylinder Installation

Now that we have 4 Wheel Disc Brakes installed on our 1971 Super Beetle we need to install a master cylinder that can supply the appropriate amount of fluid to the calipers. The installation is quite simple and takes just a few tools. Bleeding the brakes afterwards will take more time but we’ll address that later as we’re going to be pulling the body off soon.

Wow this is perfect. I have a 71 vw buggy with drum brakes that are not in good shape, I’m glad this series is here to help with the disc conversion process

[damianjuarez]

Can i switch the position of the brake switches with the brake lines? Having space issues on a 73 super

Hi Sam. When doing a disk brake conversion up front and leaving the stock drums in the back, what style master cylinder is

[BeatleBaly]

Both of my switches leak... Even with teflon! Help!!

[djjonnybong]

Will a large bore be ok to install with just the front brake upgrade if i already need to replace the cylinder?

[TEDodd]

How does this master cylinder work with 4 wheel drums?

[lakehighland]

Why would you not bench bleed before the install?

[kirwankars]

You HAVE to bench bleed the master beforehand
