Now on to the rear. I found the rear caliper to met my needs and no need to change just paint black. I did find that I had to make concentric rings for the rotor to hub.Here they are being made on the lathe.

Ok I'm going to have to make a disclaimer here because this is my car and I work on it how I please. This write up does not imply that this is the only way to do this or the best way.Just way I did it. That said,on we go.

Here they are done.

I also made the new taller caliper mount plate kit so rotor won't hit the caliper.

The caliper plates and concentric ring mocked up.

You also have to clearance the caliper mount for the rotors O.D. Don't go to deep because you'll break into the pin slide area and you dont't want junk getting in there.

This is the new stuff.

So that wraps up the brakes.
 
I did all these mods years ago. They where all posted over on that other nazi site that i'm banned from now.
 
dead thread revival!!
got a question?
how did you add the needed clearance on the caliper bracket?
like in this pic:

Milling machine IE Bridgeport. I was like wow whats this doing up here. LOL There was alotta number crunching and planning to get these where I wanted them.
 
All you did was put in bigger rotors, this will help with cooling-some, but no real braking force gains simply because the calipers are so tiny

I'm not saying it's not good work...it LOOKS nice.. But why so much effort for not much reward?

yep. i have the rears only. no difference that i can tell. and i hear the mark calipers are bigger than cobra rear calipers.
still saving up for the fronts.
its for looks. and while it is a lot of effort, it isn't too terrible much money. in my case, simply the price of rotors.

Is this to me?
 
here you go.

The disk size has two items to address: diameter and thickness. The diameter is easier to understand and easier to see. As a simple rule, the larger diameter of the rotor, the more force that is available to stop a wheel, just like using a longer wrench makes it easier to break a frozen bolt loose. If you kept the same caliper and same pads, but installed a larger diameter rotor, you would get greater stopping power. This power can be referenced in Newton-meters of torque. Factory rotors are sized according to many factors: wheel sizes, calipers used, unsprung weight, tires, price, etc. Initially, it would seem that the largest diameter rotor that can be obtained should be used, but those other factors must be kept in mind. Even, a reasonably larger diameter rotor will provide increased stopping power.


I didn't want to write all that out so I stole it from a brake webpage.

rear braking on our Marks are almost nothing to worry about if you used a heat gun to the rotors after a hard highway speed braking to a complete stop...heat makes it hard to brake, picture a small frying pan getting heated up on the stove verses a larger pan...so, main worries should be concentrated on the front rotors
 
IMHO, bigger is always better.

My Focus is gonna be getting Cobra brakes one of these days. Its just as much fun to brake quickly as it is to accelerate quickly.

I restored a cooper and it was no problem to run a through the cones the width of parking spaces like that at a decent speed.
When an excursion passed you at 80 on the freeway hold on to the wheel.. if it was a semi.. your wishing for big brembo brakes and a bigger wheel to hold onto.
 
No need to call.


I'm thoroughly happy with the current handling. The brakes need to be bigger, and a small Turbo hung off the front of the engine.
