Rewind Disc Brake Caliper Pistons with This 3-Piece Tool Set
This three-piece tool set makes rear disc brake pad replacement straightforward, handling the piston retraction step that typically calls for specialist equipment. The knurled T-bar rewind tool drives the piston back by rotating clockwise, using a threaded carbon steel body that gives positive, measurable control. The round alloy reaction plate seats on the piston face and distributes load evenly to protect the piston seal, while the black steel brake pad spreader gives you a second point of leverage when easing old pads free from the bracket. Constructed from solid carbon steel with an anti-rust finish, the set handles repeated brake service use without corroding or deforming. Suitable for most European and Japanese vehicles fitted with right-hand-thread rear caliper pistons.
- Threaded Rewind Mechanism: T-bar drives the piston back by rotating clockwise, matching right-hand-thread rear calipers on most European and Japanese cars.
- Alloy Reaction Plate: Distributes force evenly across the piston face during retraction, protecting seals and the piston surface from damage.
- Carbon Steel Construction: Anti-rust finish resists corrosion so the tool set stays serviceable on the shelf between brake services.
- Three-Piece Set: Rewind tool, reaction plate, and C-profile pad spreader cover every step of the rear pad replacement process.
- Knurled Grip: The textured body gives positive hand control even when working with brake fluid on gloves.
Disc Brake Caliper Piston Rewind Tool Set
Replacing rear disc brake pads requires winding the piston back into the caliper — a task this three-piece tool set handles cleanly. The T-bar rewind tool uses a threaded carbon steel body and knurled grip for positive, controlled retraction. The alloy reaction plate spreads load evenly across the piston face to avoid damage during the wind-back.
Built from solid carbon steel with an anti-rust finish, the set is designed for repeated workshop use and suits most European and Japanese vehicles with right-hand-thread rear caliper pistons.
What's Included
- 1 × T-bar caliper piston rewind tool (chrome knurled body, right-hand thread spindle)
- 1 × Round alloy reaction plate with centre bore
- 1 × C-profile steel brake pad spreader
Compatibility
Fits rear disc brake calipers on most European and Japanese cars with right-handed thread pistons. Check your caliper specification before use on left-hand-thread or non-threaded pistons — some BMW and VW-group rear axles use the opposite thread direction.
