The male dry bleed valve is fitted in place of the bleed screw, and once fitted there should be no need to loosen or remove the coupling unless it is being replaced. The male dry bleeder is basically a valve that is opened when the female bleed valve coupling (CP6300-31 or CP6300- 32) is connected to it. The female coupling is connected to a bleed pipe and container, allowing brake fluid to be pushed through the system to bleed it. The CP6300-32 bleed coupling is designed for use with standard plastic bleed tubes and incorporates a non-return valve for one man bleeding. Another advantage of the dry bleed system is that it removes the possibility of introducing air into the system via bleed screws, when vacuum bleeding. The dry bleed caliper fittings are available with M10 x 1.0mm (CP6300-21) or 3/8” UNF (CP6300-27 or -30) threads. When fit- ting the dry bleed valve in to the caliper, a small amount of Loctite 270 should be applied to the thread and the coupling tightened to a torque of 13Nm. Seal kits are available for the male dry bleed valves. See table below for part numbers. Important Note: Fitting the dry bleed system may affect the radial profile of the caliper. It is therefore essential that the clearance between the caliper assembly and wheel is checked carefully prior to running the car.

I NSTRUCTIONS FOR ASSEMBLY OF CP6300-21, -27, -28, 30 & -37 DRY BLEED VALVES - For latest installation drawing please visit www.apracing.com. Note - Lubricate ‘O’ Ring Seals with clean new brake fluid. ◘ Stage 1 - Fit ‘O’ Ring seal to plunger. ◘ Stage 2 - Slide plunger and spring into bore. ◘ Stage 3 - Apply a small amount of loctite 270 to the spring retainer threads & screw until flush with end of bore. Should screw up flush to the end of body. When tightening spring it should push plunger near to flush at the other end of the body. ◘ Stage 4 - Fit anti-extrusion ring & ‘O’ Ring seal to outside of body. ◘ Stage 5 - Fit ‘O’ Ring seal and cap to outside of body. NOTE: ◘ For CP6300-21 The ‘O’ Rings in stage 4 & stage 5 are the same. ◘ For CP6300-27 & -30. The ‘O’ Ring for stage 4 is different to stage 5.
