Sorry if this is the wrong section, but I thought this subject is not specific to one make of bike and would get more chance of getting a reply in this section. 

 

The new style Braktec monobloc brakes have two covers on the front face (as seen in the attached photo), which look like Torx, but the size of Torx wrench has me stumped, on where to get that size. Anybody else removed these covers, what tool did you use please?

Thanks for your assistance. 

Cheers

That is a really good idea. Years ago I made a torx key out of an Allen key with a bit of judicious grinding, in the days before torx bits became readily available.

I used a long 12mm bolt with the hex sides shaved down to fit. Grip the bolt in a vice, turn the caliper around it, or use 2 nuts as lock nuts on the bolt threads and use a spanner. 

I doubt they are a standard tool. The ISR road race caliper said have a similar setup and you can buy the tool for removing the caps as well as servic kits from ISR. Even then there are different size tools for different sized pistons. 

Why do need to take the caps off? 

Well thanks for all your useful information, I was hoping there would be an actual tool that Braktec recommended, but haven't had a reply from them yet! Surely the Trials teams that use this must know?

 

I want to remove the caps, pistons and seals, so I can get them powder coated a particular colour. 

 

Thanks again for your thought and if and if I ever do a get a reply from Braktec, I'll let you know. 

Torx T100 is the size. Braktec Tool Part # RP600013013

 

If torx T100 isn't available, be careful with improvisation a new tool since it can damage the finish. Protect it with a rag between tool and part. Probably a big nut will be able to turn this cap. Below the one I've made to formula brakes.
