I have been looking thru the net for disc brakes and I came across this...
Honda vented disc brake kit for mini's... They allow your 10" rims to still fit and are the equivalent to cooper s brakes?
I was wonder if any one has done this conversion or knows a bit about it, is it worth it or not?

I have fitted solid Honda Civics rotors & calipers to Minis with 10" wheels but won't do them any more.
The pads need to be trimmed severely or they hang over the inside of the rotor and wear funny.
And the calipers and their mounts need a bit of trimming with the angle grinder.
And many wheels (including ALL the steel ones) will not fit.

These mods would ring alarm bells if you want them engineered.
Much the same comments would apply to Honda vented ones, they are just wider.

If fitting to 12" wheels or bigger these comments do not apply.

Another problem is they are using the drum brake CVs and drive flanges- these are nowhere near as strong as the disc brake type found on S and late UK Minis.
OK for the road I guess, but I'd want better for track use. :wink:

C'mon Hutto, for the price of a real set of mini disc brakes these days, would you really bother going any other way?

Are you doing this just 'cause i cooked your brakes last weekend? :oops:

Send sswannab a PM and see what he paid for a set of cooper s discs from steve... Lil' Bastard got 'em REAL cheap. Not that i'll mention any figures here.

I know that I am a little late to this discussion, but I thought that I could add a little bit.

I used brakes off of an '87 civic sedan 1.5L, manual trans. All of the parts new cost me $180 U.S. Everything fit great, with little work. I didnt cut the rotors down like people have done, the only thing that I did was trim the inner sholder of the drive flanges down so that the rotors will fit flat. The brake lines threaded up and pedal travel and force is not abnormal. My mini has 13 x 7 wheels, which helped with the fit of the brakes (a 87 civic also has 13" rims). Other than putting conventional springs on the car, this change made the most difference in the behavior of the car. I would recommend to anyone who want has drum brakes on the front. I autocross my car a few times a month and I have had no problems with the brakes.

The kit is easy to make, and can be done with a drill press and an angle grinder.

I'll do my best to explain. Just so that we are on the same page, the drive flange is where the wheel actually bolts to, where the studs are located. The flange has an inner lip that fits on the inside of the drum, where the drum meets the flange. The drums ID is slightly larger than the ID of the disk. So, you can either cut the drive flange, or enlarge the ID of the disk. When I say cut the flange, I mean make the flat machined area larger. I chose to cut the flange, so that down the road I could get rotors off the shelf and just bolt them on without any worry. I had to remove about .125" of material to make everything work.


I can attach pictures if there are still questions as its hard to explain without pointing at something.

Attached is the brake bracket that I copied. Its not mine (mine is nicer of course :) ) but it will give you guys an idea.

Oh.... so you are using a drum brake assembly and converted it to accept a rotor and a caliper?

When I say "drum brake assembly", i mean

Uprights
Flanges
Driveshafts
Steering arms

And youve removed the backing plate, then use the 3 backing plate mount nuts to hold the caliper bracket.

Right?

No original mini disc components used?
