4 Pcs Bicycle Disc Brake Pads Adjusting Tool Mounting Assistant Brake Pads Disc Brake Pads Alignment Tool (Arc and Ellipse Shape)

Easy to use, aligned my calipers and work for road bikes and mountain bikes. Super cheap for how functional and practical they are. A must have for every cyclist.

Described as in the specs but I used mi sight instead.

This is an essential tool for centering the brake calipers and adjusting the brake pad clearance. I keep one in my saddle bag, too.

These work well but I find that the oval ones are better - they reach into the brake pad area better. The more rectangular ones seem to get bound up as the bridge piece (that connects the two sides together) doesn't go into the caliper all the way. The oval ones have more reach.Maybe your experience will be different but either way, these work well and make quick work of aligning brake pads.

Works great and its nice to have the two different shapes to work with to accommodate different disc setups.

You can use a couple of business cards or index cards to provide additional space when centering disk brake pads on a bike. But these are so much easier and consistence.May not need these often on my personal bikes, but I also have used them as part of my job with new bike assembly.

Great tool. Does what it’s supposed to and great price.
