StopTech Stainless Steel Braided Brake Lines provide a quicker; firmer; more consistent pedal response by maintaining consistent brake pressure. Additionally; stainless steel lines provide precision brake modulation; especially during threshold braking. The improvement in pedal feel is more dramatic on older vehicles where the factory rubber line may have softened and swelled due to age. A variety of end fittings are available to meet application needs. All fittings are engineered for proper fit and durability. All necessary brackets and fasteners are included with each line kit. PTFE inner liner is resistant to expansion under pressure. Stainless steel woven braid provides support and resistance to impacts and abrasion. Clear PVC cover protects against chaffing.
