Product details
Upgrade both rear brakes of your four-cylinder Porsche 914 with Powerlite four-piston service calipers and separate MC4 mechanical parking-brake calipers. The kit includes vented rotors, flexlines and replacement parking-brake cables.
Photo note: Some photographs show earlier plain-face rotors. Current supplied-to-order kits follow the rotor specification in the selected product option.
Vehicle Fitment
| Porsche model | Years | Version / application | Required brake setup |
|---|---|---|---|
| 914-4 | 1970–1971 | Four-cylinder | Factory rear uprights and hubs; 19 mm master cylinder |
| 914-4 | 1972 | Base, four-cylinder | Factory rear uprights and hubs; 19 mm master cylinder |
| 914-4 | 1973–1976 | Base, four-cylinder | Factory rear uprights and hubs; 19 mm master cylinder |
A 19 mm master cylinder is required and is not included. Have the front and rear brake combination checked together before installation.
For a factory 914-6, a five-lug conversion or changed rear hubs/uprights, contact PMB before ordering.
A 15-inch wheel may clear, but diameter alone is not enough. Compare the exact wheel’s barrel and spokes with the wheel-clearance drawing before ordering.
What is included for both rear sides
- Two Powerlite four-piston service-brake calipers in the selected Black or Red finish.
- Two 11.38 × 0.81-inch vented rotors with the rotor adapters/hats for this application.
- BP-10 service-brake pads for both sides of the axle.
- Caliper brackets, installation hardware and braided stainless steel flexlines.
- Left- and right-hand MC4 mechanical parking-brake calipers.
- Parking-brake cable kit for connection to the existing handbrake mechanism.
| Service caliper | Powerlite; four pistons per caliper |
|---|---|
| Rotor diameter × thickness | 11.38 × 0.81 inches (approximately 289 × 20.6 mm) |
| Parking brake | Separate MC4 mechanical calipers and cables included |
Parts retained and parking-brake setup
The original compatible rear hubs and handbrake lever are retained; new rear hubs are not included. The hydraulic Powerlite calipers handle normal braking, while the MC4 calipers provide the mechanical parking brake. Correct cable routing, initial adjustment and future wear adjustment are required. Brake fluid and a 19 mm master cylinder are separate.
Questions before ordering
Does the handbrake still work?
The kit provides separate MC4 mechanical parking-brake calipers and the cable kit to connect to the original handbrake mechanism. They must be installed, adjusted and tested according to DS1568.
Are the front brakes included?
No. This is the rear axle kit. The 914 front kits are 140-17473 for 1970–1972 and 140-17474 for 1973–1976; confirm compatibility with your actual car and the complete brake system.
