Key benefits Precise brake alignment: polished stainless steel construction with precise notches keeps the tool stable during adjustment, producing consistent, repeatable disc brake alignment. Longer service life: durable material and smooth edges reduce material stress and deformation, so the tool holds its shape through repeated use. Faster, easier repairs: three openings let you adjust at different angles to reduce brake friction and speed up pad and caliper work. Safer braking performance: supports parallel piston positioning to reduce one-sided wear and help maintain even braking performance. What it does Provides three angle openings (15 mm, 18 mm, 42 mm) that fit common caliper and piston spacing to make fine adjustments without forcing parts. Polished edges and accurate notches enable controlled, low-deformation pressure on brake components. Ergonomic handle design improves grip, reduces user fatigue, and helps prevent unwanted brake noise during adjustment. Compatibility and materials Made from durable stainless steel with polished smooth edges and precise notches for reliable contact and long-term use. Flexible adjustment supports a broad range of disc brake systems and installation or repair situations. Practical applications Pad replacement: set pistons parallel and re-space calipers during brake pad installation to avoid binding and uneven pad wear. Caliper service and rebuild: use the tool to align pistons and check clearance while servicing or rebuilding calipers. Brake system installation and diagnostics: quickly adjust piston position to test rotor clearance and reduce friction before road testing. What to expect Accurate, repeatable adjustments that reduce the need for rework. Easier handling and less hand fatigue during extended repair sessions. Improved brake longevity and safer, more consistent braking when pistons are positioned correctly. Specifications Material: stainless steel Openings: 15 mm, 18 mm, 42 mm Design features: polished smooth edges, precise notches, ergonomic handle to minimize noise and fatigue A compact, durable tool for technicians and DIYers who need reliable, repeatable disc brake alignment during installation and repair.
