    Wilwood's specially formulated Hi-Temp 570° Racing Brake Fluid has a minimum 570 degree dry boiling point to withstand the severe heat requirements of automotive racing. Hi-Temp 570's low viscosity allows easy bleeding of your brake system, eliminating aeration of the brake fluid caused by foaming due to excessive pumping of the pedal. 

    This high temp brake fluid comes in a convenient 12 ounce container hermetically sealed to guarantee against unwanted absorption of moisture which can drastically lower the fluids boiling point (fluid from larger containers tends to become contaminated with moisture, lowering its boiling point and making it unsuitable for racing applications). 

    • Dry Boiling Point:  573° F
    • Wet Boiling Point:  313° F

    (Part #8352601874)
    x
                

    These in-line pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in disc brake systems. Residual pressure valves are made from billet aluminum with 1/8" npt female threads for the inlet/outlet and color coded for easy identification. Ideal for drag racing, circle track, street rod and many off road applications.

    The two pound valve is used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke. The minimal two pound residual pressure prevents fluid from flowing back without causing the brakes to drag.

                The billet SL6R series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. These calipers integrate "Big Brake" style with Wilwood's latest technology to generate big stopping power in extreme environments over a broad range of vehicle applications. The key to the superior performance of the SL6R comes from the extremely durable and efficient body design. Starting at 4.84 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. Full length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed end bridges has produced the strongest SL caliper bodies ever built. When compared to open bridge calipers that use tube or stand spacers between the body halves, the closed end bridge design is measurably stronger with less separation or deflection under load. Additional strength and resistance to deflection comes from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads without the need to remove the caliper from the mount.    A unique six-piston differential bore configuration provides balanced loading for even pad wear in sustained high heat environments. The standard SL6R calipers feature one-piece stainless steel pistons. Stainless is used for its slow he

The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight.
