What you need
Steps
Put the bike on a stand or lift so both wheels spin freely. Support it firmly before you loosen any brake bolts.
Remove the old caliper from the fork or frame mount with an Allen key. Keep the mounting bolts in a cup so they do not roll away.
Take off the old lever and its hose. Note the routing path along the bars and frame so the new hose follows the same line.
Fit the new Ultra lever to the handlebar and tighten it just enough that it stays put but can still twist in a crash.
Run the new hose along the same path and feed it through any guides or clips. Avoid sharp bends that could kink the line.
Bolt the Ultra caliper to the mount and check that the pads sit centred over the rotor. Loosen and shift the caliper if the gap looks uneven.
Fill and bleed the brake system with the fluid the kit specifies. Squeeze the lever until it feels firm and no air bubbles come out.
Spin the wheel and check for rubbing. Adjust the caliper position until the rotor turns freely with a small, even gap on both sides.
Test the brake at walking speed, then at higher speed in a safe open area. Make sure the lever does not pull to the bar.
Tips and common mistakes
Wear gloves when handling brake fluid and keep it off paint and plastic.
Check bolt torque with a torque wrench so you do not strip the caliper mounts.
Bed in new pads with a few gentle stops before hard braking.
Recheck hose fittings after the first ride for any weeping fluid.
Questions
Do I need to bleed the brakes after installing them?
Yes, a fresh install usually lets air into the line. Bleed the system until the lever feels firm and consistent.
Can I reuse the old hose?
Only if it is the same fitting type and in good condition. A new hose that matches the Ultra kit is safer and easier to route.
How do I know the caliper is aligned?
Spin the wheel and listen for rubbing. The rotor should sit centred with an even gap on both sides of the pads.
