Comma DOT 4 ESP Synthetic Brake Fluid & Xstream G30 Ready-Mixed Antifreeze (Red)
Keeping your motor running safely and smoothly isn’t just about the obvious bits like tyres and oil—it’s also about what’s under the bonnet, especially your brake fluid and engine coolant. Take the Comma BF4ESP1L DOT 4 ESP synthetic brake fluid, for example. It’s been crafted with modern motors in mind, particularly those fitted with Electronic Stability Programme (ESP). Since ESP leans heavily on your braking system to keep you steady and stop you from skidding, having a brake fluid that performs well across all temperatures is absolutely key. This stuff has cracking viscosity and high boiling points, so you get sharp braking response even when it’s chilly out—perfect for those slippery winter mornings or damp days.
Why go for Comma DOT 4 ESP brake fluid?
Well, it’s a synthetic brake and clutch fluid that ticks all the boxes for DOT 4 and SAE J1704 standards, meaning it’s spot-on for most hydraulic brake systems. Its low viscosity lets the ESP system react quicker, giving you that extra bit of reassurance when the going gets tricky on the road. And don’t forget, regularly swapping out your brake fluid as per the manufacturer’s advice not only keeps your brakes sharp but also helps prolong the clutch’s life—definitely not something to brush under the carpet.
What about the coolant then?
