Goodridge G-Stop Stainless Steel Brake Lines for 04-08 TSX

Goodridge G-Stop Stainless Brake Line Kit - 2004-2008 Acura TSX (CL7/CL9)

The first-gen TSX is a genuine sport sedan, a K24-powered, well-balanced car that people drive hard and track, and the factory rubber brake lines are the weak link when you do. Under hard or repeated braking, the rubber lines flex and expand under pressure, so part of your pedal effort balloons the lines instead of clamping the brakes, and the pedal goes soft right when you're leaning on it. These Goodridge braided stainless lines fix that: a PTFE inner line in a stainless steel braid that doesn't expand, so the pedal stays firm and consistent. On a CL7/CL9 TSX driven with enthusiasm, it's one of the most worthwhile brake upgrades you can make.

Why Braided Lines Firm Up The Pedal

Here's what's actually happening, and what these do and don't change.

Rubber brake lines flex and expand under the pressure of hard braking, and that expansion is what you feel as a soft, spongy pedal, part of your foot pressure is stretching the lines instead of applying the brakes. It gets worse the harder and more repeatedly you brake, and as the factory rubber ages.

The stainless braid around these Goodridge lines doesn't expand the way rubber does, so all your pedal pressure goes straight to the calipers. The result is a firmer, more responsive pedal with a consistent, linear feel that holds up under hard, repeated braking where rubber lines go soft. To be clear about what braided lines do: they improve pedal feel and consistency, they're not a substitute for better pads, rotors, or tires if you're chasing shorter stopping distances, but for how the brakes feel and respond, especially a pedal that stays firm through a session, the difference is immediate and genuine. On a well-balanced sport sedan like the TSX, a firm, predictable pedal is exactly the kind of sharpening-up the car responds to.

PTFE Core, Stainless Braid

The construction is what makes them firm and durable.

Each line is a PTFE inner line (which handles brake fluid and heat without degrading) inside a stainless steel overbraid that provides the firmness and protects the line from abrasion and corrosion. Stainless braided lines hold up far better over time than rubber, which cracks and degrades with age, and they look the part under the car too.

Goodridge is the name in braided brake lines, and these go through a nine-point quality-assurance process, each line tested for tensile strength and pressure-rated to 3,000 psi. They meet FMVSS 106 (the federal brake-hose safety standard), are DOT certified, and are TÜV approved, so they're properly certified, not just a cosmetic braided line.

Complete Kit, Direct Bolt-On

Everything for the install is in the box.

This is a complete set of lines with the hardware to fit them, so there's nothing else to source. The hose ends and brackets are vehicle-specific to match your factory design, so it's a direct bolt-on replacement for the rubber lines, using your factory calipers with no modification. It's a straightforward swap, you're replacing the lines one for one and bleeding the system.

They're ABS-compatible, and on ABS-equipped cars they also help reduce the pedal chatter you can feel through soft rubber lines.
