Drum Front Disc Rear Setup

Post by DesertWRX »

I’m looking for the correct master cylinder for this setup. I’ve hear that the stock single piston master works and the newer dual piston master’s work too. Does anyone here have experience with this?

Yes you can use either the single or dual master cylinder with that combo. I prefer the dual circuit master cylinder so if something happens you still will have some braking action.
One thing you may want to think about installing is a proportioning valve. That way you can adjust the brake bias. I would install it in front circuit because there is a chance of the front brakes locking up.
With the proportioning valve you can reduce the amount of fluid reaching the front disc to keep them from locking up.
Get one that is adjustable, so you can change the setting with different driving conditions.

Sure familiar with a proportioning valve. Had one on our Mazda RX3 SCCA car to cut back the fronts.

If you are going to use a proportioning valve, here is one with VW type fitting capability. No adaptors. https://www.pegasusautoracing.com/produ ... ecID=10257 Tom
