Brakes on the KISS theory

Hi All,

So I have decided my car is against me, and just when I think I have it figured out, it kicks me in the butt.

My car is a 8/75 Mk1 1300xl coupe, which at some stage of its life, has been fitted with a 1600 kent of some description (my guess is 1600GT cortina, 32 dfv carb). It also appears to have been factory fitted with a Mk2 style english axle and Mk2 rear brakes. The front struts and brakes are Mk1. It has a 1300GT style single reservior twin circuit master cylinder and booster, which I think is a 13/16".

I have decided to ditch the disk brake rear, commodore caliper capri rotor front, coil over conversion plan, and go with something much simpler.

Stock rebuilt Mk2 rear brakes with P10035 19mm cylinders on the back, and either slotted standard Mk2 rotors and rebuilt calipers with EBC greenstuff pads, or Spaced calipers and capri 2.8 slotted rotors and grenstuff pads in the front. Rebuilding the standard Master cylinder. Also using Mk2 1.6 struts with monroe inserts a lowered 170lb springs.

This is a fun street car, which might be lucky to ever see either a drag strip or hillclimb once in its life. At some stage in the future, it might get its 1600 upgraded to a mild pinto.

What are your thoughts guys? opinions wanted! Is the vented upgrade a waste? Bendix ultimates better for the street? Different wheel cylinders?

Vented will give you absolutely no more stopping force than the solid disc when using the same (spaced) calipers. Only benefit is that fade is greatly reduced when racing. If you're driving normally on the street then you shouldn't need them. I don't know if you can get plain slotted rotors, but that would be my first upgrade for the street.

RDA would do a slotted rotor.
RDA118S would be the part number I'm guessing. Worth giving them a call.

I have run solid disks on the streetcar, with no dramas.
The third hot lap around Lakeside is a different story.

Getting extended length drum shoes worked for me.

MAXRS does any normal brake place do these extended brake shoes?
My dad is keeping the drums in his car for originality, and doesn't want to go disc.

I had to send the drum shoes, down to Sydney to be done.
My local mechanic put me onto the custom brake lining mob.
I can find out the business name and phone number after Easter.
