Disc brake caliper installation

Disc brake caliper installation


Begin with checking the frame holes for mounting the brake adapter. Confirm the bolts will pass through the holes and turn freely.

If not, use 200 grit sandpaper rolled up to remove the buildup of powder coat paint.

Note: Try to evenly remove paint buildup.

The bolts provided with the calipers have thread lock already installed. However, for this initial install we will not be tightening the bolts yet. Just snug them by hand where they still have the ability to move.

Note the orientation of the adapter. This is important to duplicate. (They are not symmetrical)

Install the front adapter as shown (again note the orientation).

You may need to purchase screws for mounting the calipers to the adapters. They are the same size and length as the one used to mount the adapters to the frame (M6 x ?).

I purchased stainless steel ones and painted the heads and washers black.

The calipers come with a fixture block installed between the brake pads. Leave this orange plastic piece in place until later (when we mount the wheels). The plastic fixture block prevents someone from squeezing the brake handle and forcing the pads together without a disc in between them. (the reason is they are very difficult to get apart if that happens)

Note the routing of the front brake line in the photo below. Left handlebar lever goes to front brake. Don’t worry about the extra hydraulic line length. For now just let it run free near the handlebars. We will trim the hydraulic lines in a different section.

Install the front caliper onto the adapter as shown. Note the orientation.

Secure the hydraulic line to the fork with a ty-wrap through the fork weld on eyelet.

Rear brake caliper install


Now install the rear brake caliper onto the brake adapter. Note the routing of the hydraulic line exits the right brake handle and travels down the lefthand side of the bicycle.

Install ty-wraps working the slack out from the caliper toward the handlebars. Remember, we will trim these lines at the handlebars later.

Trim the ty-wrap ends using a pair of diagonal cutters.

Complete, proceed to mounting the wheels.
