Master cylinder question
Hey!
I have 4 wheel disc brakes on my car and the brakes are spongy. It's been recommended i get a better master cylinder. What does every one use with 4
wheel discs?

You have to fit pretty big pistons claipers for the std MC to run out of travel. Those upgraded MC's are a nice marketing ploy.
As for the EMPI rear disc kit, stick your head under the rear end and whilst a mate presses on the brakes look at the caliper bracket. This EMPI rears
have been renowned for the caliper bracket being so flimsy it bends under braking so gives a similar feel to air in the brakes. Otherwise, re-bleed
the brakes at the rear. If still having issues then clamp the 2 flexi lines at ther ear and if the pedal is hard then defo an air leak or movement in
those rears.

Probably a falcon rear disc setup
Or go back to VW and chuck some big type 3 drums on the back.

If you're IRS then NA Porsche 944 is the best rear factory disc setup you can get with a handbrake that works ( easy conversion and easily
engineered/complianced)
Next best I agree with Birdman Type 3 drums better than most aftermarket discs.

But depending what you have on the front you have to be careful with better rear brakes as you are changing the brake bias further to the rear. Most
of the rear disc kits are made so they complement the original VW discs at the front.
If however you have the heavier subaru engine in the rear then better rear brakes should complement things well as a heavier rear end requires more
rear braking force. Hence why utes/vans etc have a biasing valve that increases rear braking the heavier the load is
