HI Guys i just bought a shimano front brake caliper and the brake bolt is short so that the fixing nut goes into the forks for a neat look, however my fork s brake bolt hole is not wide enough to accept the neat bolt end and the brake bolt not long enough to pretrude to allow a normal nut setup.

is anyone else had this problem. know of any solutions or know if alternative brands work/wont work

cheers!

Did you only buy a front brake? If you have a rear with a shorter bolt, you can screw this through the front part of the fork only and this will work without drilling the fork...

Just what Pifco said, the hole at the rear needs to be enlarged to accept the allen bolt. Use an 8mm HSS drill bit thats sharp, perhaps some cooling paste if you love your forks and want the hole nice and clean and a drill at a slow/mid speed. Trusting they are steel.

Glad it's just the front - I knackered a rear brake bridge drilling out for allen bolt brakes. That was before I started getting advice from internet forums... ;)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
