DOT Brake Hose Kit Metric GM ALL42032

OVERVIEW

When you are pushing your air-cooled VW to the limit, whether it is a high-speed run down the highway or a grueling weekend session in the dunes, your braking system is the most critical safety component on your vehicle. The ALLSTAR PERFORMANCE DOT Brake Hose Kit Metric GM ALL42032 is engineered to replace those soft, spongy rubber hoses that often compromise pedal feel and response. By upgrading to these #3 stainless steel braided lines, you are effectively eliminating the "hose swell" or expansion that occurs in traditional rubber lines under high hydraulic pressure. This results in a firm, consistent brake pedal that provides the driver with much-needed feedback and the confidence to stop on a dime. For VW enthusiasts running disc brake conversions that utilize the popular GM metric calipersa staple in the off-road and performance street scenethis kit provides the perfect bridge between your chassis hard lines and your calipers, ensuring that every ounce of fluid pressure is directed exactly where it needs to go.

This kit is not just about raw performance; it is about providing a comprehensive, professional-grade plumbing solution for your custom brake setup. Allstar Performance has curated this package to include everything necessary for a seamless installation, from the high-durability 16-inch braided hoses to the specific metric banjo bolts and fresh crush washers. One of the standout features of the ALL42032 is its DOT approval, making it a street-legal upgrade that meets rigorous safety standards, unlike many off-road-only racing lines. The inclusion of frame adapter fittings, weld-on frame tabs, and holding clips means you won''t have to scavenge for extra parts or settle for a "universal" fit that looks messy or vibrates loose. Whether you are building a custom sand rail, a heavy-duty Baja Bug, or a street-legal Beetle with upgraded binders, this kit offers the legendary durability of stainless steel and the precision fitment required for modern metric braking components.

FITMENT

This kit is specifically designed for vehicles using GM Metric Calipers (typically 1978 and newer mid-size GM styles) which are the industry standard for most air-cooled VW disc brake conversion kits. Compatible models include:

• VW Beetle (All Years): When equipped with aftermarket front or rear disc brake conversions using GM Metric calipers.
• VW Karmann Ghia: Ideal for performance builds utilizing metric caliper upgrades.
• VW Type 3 (Squareback, Fastback, Notchback): Applicable for custom rear disc brake setups.
• VW Bus (Type 2): Used in heavy-duty rear disc conversions for early and late Bus models.
• Dune Buggies & Sand Rails: The standard choice for rail frames using GM-style braking hardware.
• Baja Bugs: Provides the necessary length and durability for long-travel suspension setups.

PRO TIPS

1. Verify Suspension Travel Clearances

Before you finalize your installation, it is absolutely vital to cycle your suspension through its full range of motion. On a long-travel Baja Bug or a Sand Rail, the distance between the frame tab and the caliper can change significantly. Ensure that at full droop, the 16-inch hose is not being pulled tight, as this will eventually lead to fitting failure. Conversely, at full compression, make sure the hose does not kink or rub against the tires or shock absorbers. Use the included frame tabs to position the junction point in a location that minimizes hose movement during steering and suspension cycles.

2. Always Use New Crush Washers

While it may be tempting to reuse old copper washers, we strongly advise against it. Copper crush washers are designed to "work-harden" and deform once to create a perfect high-pressure seal between the banjo fitting and the caliper. Once they have been compressed, they lose their ability to seal effectively a second time. This kit includes four fresh washersuse two per side (one on each side of the banjo fitting). Torque the banjo bolts to the caliper manufacturer''s specifications, usually between 12-14 ft-lbs, to ensure a leak-free seal without stripping the metric threads in the caliper housing.

3. Proper Bleeding and Fluid Choice

When installing these stainless lines, you are introducing a significant amount of air into the system. Start your bleeding process at the wheel furthest from the master cylinder (usually the passenger rear) and work your way closer. Because these lines are #3 diameter, they can sometimes trap small air bubbles at the high points of the hose loops. Ensure the hoses are routed without "high loops" that sit above the bleeder screw level if possible. Additionally, since you are running high-performance stainless lines, we recommend using a high-quality DOT 3 or DOT 4 fluid to handle the increased heat that disc brakes generate compared to old-fashioned drums.
