Goodridge Stainless Steel Braided Brake Line Kit – October 1990–1998 BMW 325 / 328 (E36) | PTFE Inner / Stainless Steel Outer Braid

The Goodridge Stainless Steel Braided Brake Line Kit for the October 1990–1998 BMW 325 and 328 (E36) is a complete brake line kit that replaces the factory rubber brake hoses with Goodridge's stainless steel braided lines — featuring a PTFE (polytetrafluoroethylene) inner liner and stainless steel outer braid that eliminates the spongy pedal feel caused by rubber hose expansion under braking pressure, delivering greater braking efficiency, more consistent pedal feel, and superior resistance to abrasion and corrosion. Goodridge is one of the most respected performance brake line brands in the world — a UK brand with decades of motorsport and performance aftermarket experience supplying stainless braided brake lines for a wide range of performance vehicles.

Key Features:

• PTFE inner liner — polytetrafluoroethylene inner liner provides a smooth, non-reactive bore for brake fluid — PTFE does not absorb moisture like rubber, does not degrade from brake fluid contact, and provides a consistent bore diameter that does not expand under pressure
• Stainless steel outer braid — stainless steel braided outer sleeve provides superior resistance to abrasion, corrosion, and physical damage compared to rubber hoses — the braid also prevents the hose from expanding under braking pressure
• Eliminates spongy pedal feel — the defining benefit of stainless braided brake lines — rubber hoses expand slightly under braking pressure, absorbing pedal travel and creating a spongy, imprecise pedal feel. The stainless braid prevents this expansion, delivering a firmer, more direct, more consistent pedal feel
• Greater braking efficiency — more consistent brake fluid pressure delivery to the calipers — the braking force applied at the pedal is transmitted more directly to the calipers without the energy loss of rubber hose expansion
• Superior abrasion and corrosion resistance — stainless steel braid and PTFE inner resist the abrasion, UV exposure, and corrosion that degrade rubber hoses over time — a longer-lasting solution than the factory rubber hoses
• E36 BMW 325/328 specific — engineered for the October 1990–1998 BMW 325 and 328 E36 — correct hose lengths, end fittings, and routing for the E36's brake system
• Goodridge quality — manufactured by Goodridge, one of the most respected performance brake line brands in the world with decades of motorsport and performance aftermarket experience

Why Upgrade the E36's Brake Lines?

• Rubber Hose Expansion: The factory rubber brake hoses on the E36 BMW expand slightly under the hydraulic pressure generated during braking — this expansion absorbs pedal travel and creates the characteristic spongy pedal feel that affects rubber-hosed brake systems under hard braking. On a 30+ year old E36, the factory rubber hoses have also been subjected to decades of heat cycling, UV exposure, and brake fluid absorption — further degrading their performance and increasing the risk of hose failure.
• Stainless Braid Advantage: Goodridge's stainless steel braid prevents the hose from expanding under braking pressure — all pedal travel is converted directly into brake fluid pressure at the calipers, not absorbed by hose expansion. The result is a firmer, more direct, more consistent pedal feel that gives the driver more precise control over braking force — particularly under the repeated hard braking of track day and performance driving conditions.
• Track and Performance Use: For E36 owners who use their car on track or in autocross, stainless braided brake lines are a fundamental safety and performance upgrade — the consistent pedal feel and improved braking efficiency they provide are particularly valuable under the repeated hard braking of track conditions where rubber hoses heat-cycle and expand progressively.
• Street Use: On the street, Goodridge stainless lines provide a more confidence-inspiring pedal feel and eliminate the concern of aged rubber hose failure — a meaningful safety upgrade for any E36 that is driven with purpose.

Specifications:

• Construction: PTFE inner liner / stainless steel outer braid
• Application: October 1990–1998 BMW 325 / 328 — E36 chassis
• Weight: 0.1 lbs (shipping weight — brake lines only)

Fitment Information:

• October 1990–1998 BMW 325 — E36 chassis (325i, 325is, 325iC, 325iX)
• October 1990–1998 BMW 328 — E36 chassis (328i, 328iC, 328is)
• Verify fitment for your specific E36 model year, body style, and brake system configuration before ordering — confirm that GRI31003 is the correct brake line kit for your specific E36 325/328 variant. The E36 was produced in multiple body styles (sedan, coupe, convertible, touring) and some variants may have different brake line routing requirements.
• Note: Professional installation by an experienced brake system specialist strongly recommended — brake line replacement is a safety-critical procedure that requires correct fitting installation, correct torque specifications, correct brake system bleeding, and verification of correct brake system function before driving.

What's Included:

• Goodridge stainless steel braided brake line kit — October 1990–1998 BMW 325/328 E36 (GRI31003)
• Refer to Goodridge's product documentation for the complete list of lines included in the kit and their routing locations

Installation Notes:

• Professional installation by an experienced brake system specialist strongly recommended — brake line replacement is a safety-critical procedure
• Bleed the brake system completely after installation — any air in the brake system after line replacement will cause a spongy pedal and reduced braking performance. A complete brake system bleed is required before driving.
• Inspect all brake system components (calipers, brake pads, rotors, master cylinder, ABS unit) before installation — a brake line replacement is the correct time to address any other worn or degraded brake system components on a 30+ year old E36
• Torque all brake line fittings to the correct specification — under-torqued brake fittings will leak under braking pressure. Over-torqued fittings can damage the fitting seat and cause leaks.
• Verify correct brake system function — firm pedal, correct pedal travel, no leaks at any fitting — before driving the vehicle
• Use the correct brake fluid specification for the E36's brake system — verify the correct DOT rating and fluid type before bleeding
