Bike Disc Brake Pad Spacer And Spreader
A two-ended bike disc brake tool. One end is a flat 2.5 x 16 mm blade that sits in the caliper slot while the wheel is off, so the pistons can't creep shut during transport or when the lever gets bumped. The other end is a 16 mm wide wedge that tapers from 2.0 to 5.0 mm over 40 mm and pushes the pads back apart before you refit a 1.8–2.0 mm rotor. The 168 mm red handle has knurl grooves and a zip-tie/lanyard slot so you can tie it to the brake lever and see it before you ride off.
Flagged: hydraulic brake system. Not for safety-critical use without independent engineering review.
Stepped Brake Piston Bleed Block
A four-step sacrificial bleed block / pad spacer for hydraulic disc brakes: slide it into the empty caliper and stop at the thickest step that fits (9, 11, 13 or 15 mm) to hold the pistons fully retracted while you bleed or swap pads. 99 x 26 x 15 mm with 45-degree lead-in ramps on the nose and every riser, 1-4 dimples marking each step's thickness, and two 5.5 mm M5 holes on 10 mm centres in the handle so it hangs on a hook or screws to the toolbox lid.
