Proportioning Valves

Knob Style, Single Inlet & Outlet.

This adjustable proportioning valve combines the latest refinements to deliver precise pressure metering and strength from a compact forged billet design. Pressure adjustments range from 100 - 1000 PSI and provide for a maximum decrease of 57% in front to rear line pressure, the most of any available valve. Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure. Valve weighs only 5.2 ounces and has two .25” side mounting holes. Easy to install as the valves inlet and outlet ports are 3/8-24 SAE inverted flare seats.

Combination Proportioning Valve

The Combination Proportioning Valve substantially simplifies mounting, plumbing, wiring and brake proportioning adjustments on vehicles with dual circuit braking systems. The combination block maintains full isolation between front and rear fluid circuits and can be used in conjunction with any tandem outlet or dual mount master cylinder assemblies. The rear circuit has a single inlet and single outlet with the adjustable proportioning valve. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in front to rear line pressure, the most of any available valve. Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure. The front circuit has a single inlet with two outlets. It can be run as a single outlet with one outlet plugged, or used to split the plumbing on its way to the front brakes. A fluid port with a brake pressure switch responds instantly in the front fluid circuit for brake light activation. A wiring pigtail and a protective boot is included with the kit. Easy to install as the valves inlet and outlet ports are 3/8-24 SAE inverted flare seats.

Tilton lever-type proportioning valves enable adjustable brake line pressure reduction to a particular wheel or wheels. They can also be used effectively with single or dual master cylinder systems, providing better front-to-rear brake balance under both light and heavy braking.
Tilton’s lever-type proportioning valve provides a visual reference for seven distinct positions:

Seven notched pre-determined pressure positions
Wide clearly labeled handle
Precision-machined billet aluminum body with standard AN-3 ports

  These are bolt-on kits and comes in several stages for road or race applications. The full kits come complete with new discs, calipers, pads, hubs in some cases, fitting kit and full instructions with installation photos. All you need to install is time and tools.

These Big Brake upgrade kit is designed to exceed the performance of the factory OE brakes in two key areas: First, larger diameter rotors which increase heat capacity, allowing a driver to brake harder stop-after-stop while reducing chance of brake fade. Second, stiffer lightweight billet 4 piston calipers and stainless steel lines reduce system compliance while providing a consistent pedal feel and very confidence inspiring brake responsiveness.

The key, however, is to increase heat capacity and reduce compliance without upsetting the vehicle's stock front-to-rear brake torque ratio which precisely apportions front and rear braking resources while factoring in vehicle weight transfer under braking.

In contrast, a brake upgrade that adds too much front torque (as many do) will reduce your car's ability to maximize the traction available from all four tires, robbing you of performance. In addition, a system that uses pistons that are too large will make the brake pedal much more difficult to modulate, limiting a driver's control of brake input. All of these elements have been optimized in the Ol Phartz Partz Big Brake kits.

Combining the largest rotor possible to fit under standard factory wheels and four piston billet calipers, the Ol Phartz Partz Big Brake kits represent the next generation of braking for your British sports car.  These kits have calipers that provide low-maintenance performance, a huge weight savings, and high temperature capacity for both street and track.

These Big Brakes fit snugly inside production wheels and a many aftermarket alloy wheels. Some of the factory steel wheels will require a wheel spacer for caliper clearance, this will be noted with each kit. Our kits contain DOT compliant stainless steel braided brake lines along with a complete hardware package for a safe and easy DIY install. All of the kit hardware is grade 8, stainless or military specification.   Cross-drilled or slotted rotors are available at an additional charge.

The original oil filters were felt. We have been able to get some of these filters. Two manufactures of oil filter were used over the course of time, Tecalemit and Purolator. Fortunately the elements for both will interchange. They do, however require different sealing gaskets. Our filters have both thickness of sealing rings in the package. This filter was used on early "B" series engine elusively throughout the 50's and 60's and is a good alternative to the GFE102 paper filter.

These pumps have the same aluminum housing with the deep cast impeller and the by-pass hose take off. This higher capacity was original equipment on the 1098cc engines and more coolant then smaller impeller pumps on the 948 engines These water pumps have the much larger impeller, it sticks into the block very slightly more than 1/2"(14.03mm). This water pump will fit all 1098cc blocks and the small bore block 948cc.
FITS:

Morris Minor 1963-1971
May be retro fitted to all earlier A-Series Engines for more capacity.
