Frequently Asked Questions
Q: What types of disc brakes is this alignment tool compatible with?
A: This disc brake alignment tool comes in two shapes. The rectangular version is compatible with 2-piston and 4-piston disc brakes, while the oval version is compatible with 2-piston, 4-piston, and 6-piston disc brakes — making it a versatile option for most mountain bikes and road bikes with hydraulic or mechanical disc brakes.
Q: How do I use the disc brake gap alignment tool?
A: Simply insert the tool between the brake rotor and the brake pads before tightening the caliper mounting bolts. The tool acts as a spacer, automatically centering the caliper so both pads sit at an equal distance from the rotor. Once the bolts are tightened, remove the tool and spin the wheel to confirm smooth, rub-free rotation.
Q: Is this tool durable enough for regular use?
A: Yes! The tool is made from 304 stainless steel, which is highly resistant to impact, bending, and corrosion. It's designed for repeated use and is lightweight enough to carry on every ride without adding noticeable weight to your kit.
