Rated 5 out of 5 by These parts made for a VERY easy brake rotor size upgrade from 180/160mm to 200/180mm With a little help from the Techs and Chainreaction Cycles I managed to do a brake upgrade from 180/160mm to 200/180. It was not only cheep but easy too. For my setup I needed a Avid 40 Post mount and screws. The screws were needed as were all the other mounting parts current setup - so make sure you order a kit with screws. The new rotor came with mounting screws meaning the only bits left over were the 140mm rotor and the old rotor mounting screws. The numbers in the notes below refer to the image. Left is before, right is after. 1. The 180mm front rotor becomes the new 180mm rear rotor 2. The front post mounting bracket becomes the new rear mounting bracket note the smaller end is at the rear and the bigger end at the front (I hope I got this right) 3. The front post mount screws become the new rear mount screws 4. The rear post mount screws become the new front screws that connect the brake caliper with the new mounting bracket 5. The new 200mm front rotor 6. The new 40P front mounting bracket and the 2 small screws that came with the mounting bracket Step 6 was probably the most confusing. If you look carefully you can see that the mounting bracket is screwed into the fork (step 6) and a different set of screws attach the brake caliper to the mounting bracket (step 4). 14 June 2014

Answer: 
The mount size required will depend on which rotor size is going to be used in conjunction with the brake caliper.

Answer: 
The older Hope Mini brakes used pre-set calipers for the rotor size (#3 was a 185mm IS mount). To mount IS caliper to a Post mount frame/ fork you need to use the adaptor below, which causes a 20mm increase in rotor size. If you fit the #3 caliper you will need a 205mm rotor. Alternatively, you could replace the #3 caliper with a #5 (165mm IS) and then use the mount below will fit to a post mount fork using the 185mm rotor you began with.
These calipers can be difficult to track down though; a new brake would be the most futureproof approach.
