Description
This is a Left Hand Rear Brake Hose made by Girling in the UK for a Triumph TR4A IRS, Triumph TR250 and Triumph TR6. One end of the brake hose screws into the junction block and is sealed with a copper washer, the other end attaches to a hardline. ***Installation, because of the tight area to work in it makes it much easier to reach back into the wheel well with a 12 to 14 inches extension and use a 9/16 crowfoot wrench. This will allow you to move the hose more that 1/8 o f an inch at a time.*** This hose is inches Long and has 3/8 x 24 fitting nipple style on one end and 3/8 x 24 fitting that seals with a copper washer on the other end.

Brake hoses are composed of multiple layers of rubber-like material and reinforcing cords, each tailored to withstand specific stresses. The innermost layer, which comes into contact with brake fluid, ensures the fluid is securely contained for smooth operation. The outer layer protects the hose from exposure to oil, grease, ozone, road debris, and other environmental elements. A layer of reinforcement, such as a cord, is embedded between these layers to provide the necessary strength to endure the high pressures brake systems generate. If a brake hose fails, it can lead to complete brake system failure, which is a serious safety risk.
Over time, brake hoses can deteriorate in several ways. One of the most common issues is the breakdown of the outer jacket, often caused by ozone exposure, which leads to oxidation and brittleness. This wear can often be detected visually or by touch—rubbing a deteriorating hose will leave black residue on your fingers. Additionally, small dry rot cracks may appear when the hose is bent, signaling that replacement is necessary.
Inner liner ruptures can also occur, usually due to age or damage, such as pinching the hose with tools during repairs like caliper or wheel cylinder replacements. When the inner liner is compromised, it may result in bulging or bubbling of the outer layer due to high pressure. In some cases, the damage may not be outwardly visible, as brake fluid can seep between the layers, causing the brakes to stick or fail to release properly.
Although brake hoses generally last for many years, regular inspections are crucial. At a minimum, they should be checked during every brake service, and for older vehicles, during each oil change, to ensure they remain in safe working condition.
