Replace your brake fluid reservoir cap for improved pressure equalisation and stunning appearance.
The RacingLine Brake Fluid Cap will hold your brake master cylinder at perfect pressure equalisation to ensure that your high-performance braking system is performing exactly as it should.
Especially with big brake kits on track, rapid pad wear can create negative pressure in the master cylinder
Our replacement Brake Fluid Cap has a better pressure equalisation system than the factory cap, ensuring zero pressure variance
This is an engineered, billet replacement coolant cap to replace the cheap plastic one.
Don’t confuse this RacingLine full replacement cap with other cheap covers – which simply stick on over the plastic cap. We think your car deserves better than that.
Each cap starts life as a solid billet of aerospace-quality 6061 aluminium
Polished, then gloss-anodised in stunning Midnight Black to stay beautiful for year after year
with the latest CNC 5-axis technology
Breathing system ensures perfect pressure balance
