These rebuild kits fit Wilwood and Tilton universal master cylinders. Available bore sizes include: 5/8", 3/4", 7/8", 1", and 1-1/8".
Tech Tip: The bigger the master cylinder, the more fluid you get... but you'll have less pressure at the caliper.

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

Ultra Lite Brakes Hot Fluid is an extreme service racing brake fluid. This high temp brake fluid has a 600 degree plus dry boiling point which makes it ideal for severe braking conditions. Hot Fluid is a non-silicone base fluid that will not turn black like most competitive brake fluids. The fluid also has special additives that aid in lubricating and gauling. Guaranteed "O" ring friendly.
This brake pressure bleeder makes bleeding brakes a one man job. Fits Wilwood screw type master cylinder caps, many OEM manufacturer's master cylinders, and all other cars with 45mm threaded hydraulic fluid reservoir caps. Works with many Wilwood universal master cylinders, including 260-3372, 260-3374, 260-3376, 260-3378, 260-3380, and 260-5920. Will NOT work with Tilton master cylinders.Here's how it works: A tank containing new hydraulic fluid is connected to the fluid reservoir on your vehicle and pressurized with air from a hand pump (pressure gauge ensures that the hydraulic system is not damaged due to excessive pressure). When one of the bleed valves on the vehicle is opened, old hydraulic fluid is expelled as new fluid from the tank is forced into the system.
- Bleeding has never been easier!
- No need for a helper to constantly pump the pedal while you open and close the bleed valves
- Two liter tank prevents the need for constant refilling of the fluid reservoir, thereby avoiding corrosive spills
- Fast, easy and reliable one-person operation
- Works on hydraulic clutch systems, too

EXP 600 Plus is a highly refined blend developed for extreme performance under the high heat and extreme pressure of professional motorsports. EXP 600 Plus has been tested to 626° F with a wet boiling point of 417° F. These numbers far exceed any DOT or SAE specifications.
It is true that racing brake fluids need to have high boiling points. It is also true that fluids need to have low moisture affinity to slow the natural absorption rate of water vapor. But the true test of any high temp brake fluid is how well it resists aeration and compressibility after it has been heated and pressure cycled a few hundred times. The real test is at the track. EXP has been proven to maintain firm pedal feel and quick response, long after others have failed.
Note: For optimum performance, EXP 600 Plus should not be diluted with any other brake fluids. Add new fluid to a clean system.
