Hey guys,

I stumbled upon some build threads on various froums stating there is a cheaper way to upgrade to 280mm brakes. I have put together a parts list for the conversion below.

This conversion requires no rotor spacers or caliper bracket machining. It also does not require re-drilling brake rotors to 4x100!!!

This only works if you are currently running stock 262mm knuckles. If you have 242mm ones you will need to upgrade to 262mm ones first. This will work on any ED/EF/EG/EK/DC.

1. 262mm kunckles.
2. Bendix DB1206 pads or any of your choice as long as they are the same design.
3. 17CL15VN calipers and matching brackets.
4. DBA2526 or RDA7996 rotors, these numbers are for blank rotors.
5. 1 inch master cylinder with matching booster.

The rotors are from a 2007+ Mini Cooper non-S. They are 280mm in diameter, 4x100 and have the same centre bore! The lug nut holes are a little bigger but this wont effect anything. These fit perfect without issues, no modification required all bolt on!!! You do however have to slightly cut the dust sheild so it does not foul with the caliper.

The required calipers can be found on Accord V6's, Type R's, Odessy's, Legned's & Prelude's. Don't be fooled by paying top dollar for ones that came from a Type R, they're all exactly the same. You can pick them up for $50 the pair.

I paid $132 for the RDA rotors from my local parts store. you would normally pay $190-210 for the RDA 282mm blank rotors redrilled to 4x100 + $40-50 for the spacer or caliper machining. That's a saving of over $100!

I am currently doing this conversion and will post some pictures once completed. I have purchased the rotors and confirmed that they do fit without any issues.

Please bear in mind the disc/pad part numbers and pricing are reflective of the Australian market, you would have to cross reference to match it to the US equivalent.

I would like to do this, post pics please and how do we know which knuckles we have?
i think the Si, EX and LX sub models all have the bigger integra sized knuckles and the DX, HX, VX and CX all have the smaller knuckles that will not work for this mod.

Is the 1 inch bore master cylinder REQUIRED, or will the EK's 7/8 bore master cylinder suffice?
The 7/8 master cylinder will work, but you will have more pedal travel as the master cylinder is smaller. If a 1 inch is out of your budget then i would suggest a 15/16 one.

You will need knuckles that were originally 262mm, unfortunately wont work on 242mm knuckles.

Update with pictures. Sorry it took so long.

Disc mounted to the knuckle



Caliper bracket bolted on - I removed my dust shields so I didn't need to trim them



Pads installed



Caliper installed - fully assembled
