Buying Guide: What to Know Before You Buy

How HVAC Tools Are Used

Brake service is one of the most common repair jobs in automotive -- pads wear out every 25,000-70,000 miles depending on driving habits and vehicle weight. Disc brake service requires pushing or winding back caliper pistons; drum brakes require specialized pliers and hooks for spring removal and installation.

Leading Brands

Snap-on and Mac Tools produce comprehensive brake tool sets found in most professional shops. OTC (Owatonna Tool Company) specializes in automotive specialty tools and makes excellent brake service equipment. Lisle Corporation makes particularly well-regarded caliper tools for specific makes.

What to Inspect

Check the screw and thread condition on piston compressors -- stripped or corroded threads make the tool useless. Verify adapters for caliper tools are complete and undamaged. Spring tools should have intact tips and solid handles.
