Brake Hoses
Brake hoses and lines connect the master cylinder to the calipers. Over time, brake lines can eventually wear out, develop cracks, cause leaks, and even explode due to fatigue. They should be checked whenever servicing your brakes.
Brake Lines

UUC Stainless Steel Brake Lines
Original brake lines are rubber and can expand under the normal pressure of use. This expansion of the brake line negatively affects the brake caliper piston travel, and makes for mushy pedal feedback.

UUC's Stainless Steel Brake lines are used to "performance tune" your braking system.

Inner Teflon line is covered with woven stainless steel braid that will not expand under pressure. The advantages include better brake pedal feedback and a firmer pedal, along with superior brake modulation. Results will be immediate.

    Technical features:
  • fully compliant with DOT Standards (MVSS-1006)
  • lines burst-tested to 6000psi (maximum tested pressure from a BMW braking system is 1200psi)
  • Teflon inner line covered with a woven layer of stainless steel and covered in an abrasion-resistant material (translucent blue plastic covering).
  • plastic end pieces protect assembly, no exposed steel fibers to stick fingers.

Brake Master Cylinders

When you hit the brakes the master cylinder converts the motion from the brake pedal being depressed into hydraulic pressure and sends that hydraulic pressure out for distribution. If your brakes are starting to feel spongy it could be the master cylinder.

Brake Boosters and Parts

If your brake pedal is getting harder to push you may have a vacuum leak in your brake booster system. Used on power brake cars, they accept a vacuum hose from the engine manifold, and use that vacuum pressure to assist in the movement of the master cylinder.

Power Bleeders

This innovative brake bleeding device utilizes a hand pump to pressurize the brake fluid system for an easy one-person operation. A small gauge on the front of the brake fluid reservoir indicates pressure. The very large reservoir can hold about two quarts of brake fluid - more than enough for most brake flushing and bleeding jobs. The bleeder is a very useful and cost-effective tool to have in your collection. A pressure bleeder is much better than a vacuum-style bleeder because it will not cause bubbles to form in your brake lines. All bleeders come with a full 1 year warranty.
