Goodridge Braided Stainless: Most Durable

Goodridge is legendary in the world of motorsports, and their mountain bike hoses bring that same level of industrial grit to the trail. Featuring a braided stainless steel outer layer over a Teflon liner, this housing is virtually indestructible. It offers unmatched resistance to abrasion from sharp rocks and internal pressure expansion under heavy braking loads.

Because the steel braid prevents any diameter expansion, the lever feel is exceptionally firm and consistent, regardless of how much heat the fluid absorbs. This is the ultimate choice for riders who ride in harsh, rocky environments where housing damage is a common occurrence. It is essentially a lifetime upgrade for the braking system.

The trade-off is the difficulty of installation, as these kits require specific tools and attention to detail. However, for the rider who demands the absolute pinnacle of durability and performance, there is no substitute. If you live in an environment that eats gear for breakfast, make the jump to Goodridge.

How to Choose the Right Downhill Housing

Selecting the right housing comes down to a balance of weight, heat resistance, and your specific braking system. Hydraulic riders must prioritize pressure ratings and heat management, while mechanical riders should focus on compression resistance. Start by identifying whether your bike uses a hydraulic or cable-actuated system, as these technologies are never interchangeable.

Consider your riding environment when making a final decision. If you frequent rocky, high-consequence terrain, favor housing with braided reinforcement or thicker wall profiles to prevent puncture and kinking. If you are focused on weight savings and high-speed racing, prioritize compressionless systems that offer the fastest response.

Finally, ensure compatibility with your current frame’s internal or external routing. Some premium, braided housings are stiffer and less prone to tight bends, which can make them difficult to route through tight frame ports. Always prioritize a clean, stress-free route over the most expensive product on the market.

Compressionless Versus Standard Brake Lines

Standard coiled housing is inexpensive and flexible, but it suffers from a major flaw: the coil itself acts like a spring under pressure. When you pull the brake lever, the housing tries to compress, effectively “stealing” some of the force that should be going to the brake caliper. This leads to a spongy feel that creates a noticeable delay in stopping power.

Compressionless housing, by contrast, uses linear strands of steel bundled together like a bundle of sticks. Because these strands cannot compress, 100% of the force applied at the lever is transmitted to the brake. This creates a much firmer, more responsive lever feel that allows for better modulation of power.

While compressionless lines are generally more expensive and harder to cut cleanly, the performance dividend is massive for gravity riders. You gain the ability to lock the wheel with less hand effort and can feather the brakes more accurately. It is a functional upgrade that changes how the bike handles on the edge of traction.

Essential Tips for Routing and Bleeding Brakes

Proper routing is just as critical as the quality of the housing itself. Avoid tight radius bends whenever possible, as these create internal friction points that degrade performance and cause the brake to drag. Use soft, gradual curves to ensure the cable or fluid flows through the housing with zero resistance, regardless of how deep the suspension is cycling.

Bleeding a hydraulic system is not just about removing air; it is about ensuring the fluid remains clean and free of moisture. Always use the manufacturer-recommended fluid, whether it is mineral oil or DOT fluid, as mixing types will destroy the internal seals. If the lever feel remains “squishy” after a bleed, it is often a sign of air trapped in the caliper or a leak in the housing line itself.

When cutting new housing, always use a dedicated cable cutter to prevent crushing the internal structure. A clean, square cut is essential for proper fitment in the ferrules and ensures a tight seal. Take the time to properly deburr the housing ends after cutting to ensure the internal liner remains open and unobstructed.

Knowing When to Replace Your MTB Brake Housing

Brake housing should be treated as a consumable item, much like your brake pads or chain. Over time, the internal liners wear out, and the housing can become contaminated with dirt and moisture. Replace your housing if you notice excessive friction in the lever, visible kinking, or if the brake feel has become progressively mushier despite a fresh bleed.

External signs of wear also provide a clear timeline for replacement. If the outer casing is cracked, frayed, or shows signs of rusting, the integrity of the brake system is compromised. Environmental factors like constant mud exposure, extreme UV light, and frequent crashes will necessitate more frequent swaps than riding in dry, temperate climates.

Do not wait for a complete failure before performing maintenance. If your brakes no longer snap back with authority or if you find yourself pulling the lever all the way to the bar to stop, replace the housing immediately. A fresh set of housing can make an older bike feel like a brand-new machine, restoring the confidence you need to tackle the trail.

Investing time into your braking system is the best way to ensure your confidence stays high on the trail. By selecting the right housing for your specific riding style and maintaining it with care, you secure a reliable connection between your fingers and the terrain. Get your gear dialed, head out to the mountains, and enjoy the ride with full control.
