Is it dangerous to drive with low brake fluid?

Yes, insufficient fluid can introduce air into the system, causing a spongy pedal and reduced braking performance — top up and investigate the cause promptly.

Can I top up with any brake fluid?

No, always use the exact specification (e.g. DOT 4) specified by the manufacturer — mixing incompatible fluid types can damage seals and reduce braking performance.

What is the reservoir made of?

Heat-resistant, translucent plastic, so fluid level can be checked visually.

Frequently asked questions

A gradual drop is often just normal as brake pads wear (the calliper pistons extend further, drawing more fluid into the system) — but a sudden or significant drop usually indicates a leak somewhere in the system.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
