Now check your brake arm tension. The brake arms should have good spring tension, which makes them release when you let go of the brake lever. If there isn’t much tension, you may have to increase it on both sides. Undo both bolts one at a time, but don’t remove them completely....
You can also use sound to check the adjustment. There is always a base-level of noise that can be heard in every gear. This noise will increase in a slightly different way depending on which way the tension is out of adjustment. If there is too much tension you will hear a metallic ...
For instance, a long cage derailleur, reigns supreme in handling wide-range rear cassettes and the greater slack necessary when shifting to smaller sprockets or chainrings. On the flip side, short cage derailleurs are commonplace in the racing world—lighter, less prone to damage, and perfect ...
As a general rule, it’s recommended to only wind the barrel adjuster in or out by a quarter turn each time before re-checking for the best result. Step 6 You’ll now want to check the chain shifts back down to the smallest cog smoothly. If the downshift is hesitant, decrease the ...
With the freewheel stopped from moving, shift your shifter all the way in the opposite direction, as if you were going to shift to the smallest sprocket. The rear derailleur should now be stuck on the largest sprocket, which will give you enough slack to fully release the cable from the ...

Brake chambers: Cylindrical container that houses a slack adjuster that moves a diaphragm or cam mechanism Push rod: A steel rod similar to a piston that connects the brake chamber to the slack adjuster. When depressed, the brakes are released. If extended, the brakes are applied. Slack adjus...
* A "bellmouth" condition can occur in wide drums if the inner edge of the drum distorts outward. The result is uneven shoe-to-drum contact, uneven lining wear and reduced braking efficiency. To check for this condition, measure the inside diameter of the drum close to the inside and out...
Shift the bike through all gears to check for noise and ease of shifting. Repeat the process of loosening the barrel adjuster and tightening or loosening the cable as necessary to achieve the level of tension desired. Grip Shifter Remove the cover on the grip handle to expose the end of the...
1. Check the drum brake's slack adjuster for proper adjustment and functionality. When it comes to drum brakes, theslack adjusteris a critical component that connects the brake chamber push rod to the brake camshaft. It is designed to adjust the brakes automatically as the brake shoe friction...
