L brake caliper bolt size

s3nfo · 01-09-2004, 11:09 AM

Had no luck on the L forum with this, so thought I'd try it here.
Tried to do the front brakes the other day and didn't have the right tools to get the caliper off. Anybody know what size allen wrench it takes to get the bolts off?
I'm gonna replace them with regular bolts when I put the calipers back on, anybody know what size and thread those bolts are?

TIA,

I know my S was an 18mm which might befuddle some as most wrench sets go from 17mm to 19mm.

The slide pins on the calipers should be an 8 mm hex. The caliper mount bolts should be a 10 mm hex and the bolt that holds the rotor in position should be a 5 mm hex. The one holding the rotor on cant really be replaced by a normal bolt, it would stick out to much to remount the rim. The caliper slide bolts can't use a regular bolt because they only have a small portion of thread on them and the rest is smooth slide surface. That and they are likely a non standard thread and daimeter size to prevent people from using regular bolts.

I have a 18mm socket just for that job.
