Iv got all the stuff to do it in my garage. just gota rebuild it. From what i have read drums will be fine and you need to get the bias right so it doesnt step the back end out

Yep.. There isnt enough weight over the rear wheels.. You'll also find your master cylinder is WAYYYY to small for the load and you'll have loads of pedal travel.

As said, they are not essential, not even required! But extra braking power (if everything is set up properly) can't be a bad thing!

With Reyland 4 pots...I think you have more than adequate stopping power

Bigger brakes generally equals bigger slave piston volumes which means the master cylinder has to move more fluid and thus travel further

rear discs on mine
i wouldnt trust drums ever again ive got mine set to 50 percent less on the rear and havnt had a sign of it skipping the rear end yet whereas with drums it always wanted to skip me
but that might be due to having the bias valve fitted and set properly

No, I found my V6's gave massive pedal travel.

Adding rear discs acutally aided the pedal feel.

Drums look stupid, end of. Discs look better.

Do they actually stop the car any better??? No, not really, its still only 20-25% braking going to the rear (depending on load in the back). So whilst they aided my pedal feel, and stopped the arse end wanting to come round, it didn't actually make the car stop any faster.

But man do they look SO much better

tbh, money no object,

Larger master cyclinder
4 pots
braided lines all over (from MC back)
rear discs with single pot calipers
Bias adjuster.


Sorted. Stop on a dime.

mine made a massive difference to the braking of the car, was one of the best things i did IMO, the car was loads better than another corsa with exactly the same front brake set up
