About Other Brake Parts
This category holds the small parts around a brake system that do not belong with pads, rotors or calipers: the bolts and fittings that join lines to calipers, rotor fasteners, bleeder covers, levers and arms, and a few guards and coolers. Riders buy them when a fitting is damaged, when a conversion needs an adapter, or for a cleaner look.
The most common items are banjo bolts, listed in thread sizes such as M10 x 1.25 and 3/8 inch-24, and in including a double-bleed style. A banjo bolt is a hollow bolt that lets fluid pass through the fitting, and it is sealed with a crush washer. You will also see rotor bolt and nut kits, line fittings listed by thread size, a rear brake clevis, a brake arm for a Harley-Davidson trike, disc covers and guards, and carbon brake coolers. Match thread size and length to the part you are replacing.
Brands in this category include UFO, Bolt, Colony, Helix and Zeta. If you need fittings or hoses, look at Brake Lines, Hoses & Fittings. For rotors and covers, see Brake Disc Rotors and Brake Disc Rotor Covers. Seals and small repair parts are in Rebuild Kits & Parts. The whole group is Brakes & Brake Parts.
FAQs on other motorcycle brake parts
What is a banjo bolt?
A banjo bolt is a hollow bolt that attaches a brake hose to a caliper or master cylinder and lets fluid flow through it. A crush washer on each side of the fitting seals it, and the washers should be replaced when it is removed.
How do I find the right banjo bolt size?
Check the thread diameter and pitch on your old bolt or the part it screws into, for example M10 x 1.25 or 3/8 inch-24, and the bolt length. Compare them with the listing. A bolt with the wrong thread will not seal.
What should I do about rotor bolts?
Follow your manual for the torque and for whether to use threadlock. Do not guess either value. Replace damaged or stretched bolts, and tighten them evenly in the order the manual gives.
What should I do if a brake fitting leaks?
Do not ride. Check the crush washers, the sealing surfaces and the tightness against the manual's torque, and replace damaged parts. After any repair, bleed the system and check for leaks before you ride.
Does a bleeder screw cover do anything?
It keeps dirt and water out of the bleeder opening and tidies the look of the caliper. It does not replace the screw or change how the brake works.
