Useful Tools and Supplies
This article will discuss the cable (inner wire) installation in brakes. MTB levers secure to the handle bar by a clamp bolt. It is generally acceptable to secure the bolt so the lever body will move when forced. This may help prevent damage during a crash. Because the rider's body weight held by the handlebar, not by the brake lever body, it is possible to not have the body fully secure. Generally, begin alignment so the lever body is in line with the rider's arm.
MTB-type Brake Lever Cable Attachment
MTB-type brake lever.
The MTB-type brake cable uses a disc shaped end. The lever will have a fitting in lever for this disc. Typically, begin by lining up a slot in the adjusting barrels.
SRAM® levers feed from the inside through the lever body.
For Shimano® type levers, engage cable end in lever first, the fit into adjusting barrel.
Dropbar or Road Bike Type Brake Levers
The dropbar type lever body often is used by the rider to support his/her weight. This effectively makes the lever similar to a "bar-end" extension. Secure these levers fully. The body should not move, even with the full weight of the user pushing downward.
Shimano® aero-type levers body bolt is on the under rubber hood of the outside of each lever.
Campagnolo® aero-type lever mounting bolts are under the upper outside corner of each rubber hood.
The brake cable end attaches to the lever by fitting through a socket called the brake cable anchor pivot. Feed the cut end of the wire through the hole in the pivot and out the backside. If the handlebars are taped, it is necessary the housing end be aligned with the cable hole in the lever body. It is sometimes necessary to wiggle the end until you find the housing end.

Move brake lever inward as you pull back to expose cable anchor pivot of Shimano® brake/shift levers.
Shimano 7900 Levers
The brake cable installs through the front of the levers. Remove the nameplate screw and nameplate. The plate pulls away forward. Use care not to scar the exterior of the plate.
Remove nameplate screw
Pull nameplate forward from top
There is a reach adjustment screw behind the nameplate, adjacent to the cable hole. This screw turns a stud that will rotate the lever down and closer to the bars.
Location of reach adjustment screw
The lever position range from fully open to fully tightened position screw
The cable access hole is the inner hole at the lever. As seen from the front, it is the left most hole for front shift lever, and the right most hole of the rear shift lever .
