Endless RF650 Racing Brake Fluid 500 mL

ENDLESS RF650 is a high-temperature brake fluid for demanding braking in compatible systems. Its resistance to boiling helps maintain consistent pedal response when braking temperatures rise.

Consider RF650 for street, track, rally, or off-road use when it meets your brake system's requirements. Classics and occasional-use cars still need scheduled fluid changes. RF650 absorbs moisture; it is not a substitute for regular maintenance.

How much to buy

Select two or three single bottles for 1–1.5 L. Confirm your vehicle's service quantity before ordering. A bleed and a full flush can use different amounts.

Single bottle: $45. Case of 20: $791.99. The case saves $108.01 compared with 20 singles at $45 each. It can suit workshops or planned service across several vehicles. Keep unused bottles sealed.

Ground shipping

Lower 48 states and DC: $9.95 below $90; free from $90. Two $45 bottles reach the threshold before discounts. Alaska and Hawaii are unavailable.

Canada and Mexico ground rates start at $42 and depend on shipping weight. Contact us to confirm your destination. These rates cover RF650-only orders; mixed carts and discounts can change shipping. Prices are in USD; tax is extra.

Compatibility and care

Check the required fluid specification, including ABS, stability-control, and cold-weather needs. A DOT 3 or DOT 4 requirement alone does not establish RF650 suitability. Do not use it in systems requiring silicone DOT 5 or mineral fluid.

Follow the vehicle or brake-system maker's replacement schedule. Use opened fluid promptly, as the bottle directs. A high boiling point does not replace proper bleeding or brake cooling.
