Purpose and Specifications

Upgrade your vehicle's braking performance with RAP BRAKES R-LPH1 5.1 1L brake fluid, a budget-friendly DOT 5.1 synthetic formula designed for reliable stopping power. This 1-liter bottle delivers high-temperature stability, resisting boil-off during intense drives so your brakes respond sharply without fade. It's fully compatible with DOT 3, DOT 4, and DOT 5.1 systems, making it a smart choice for everyday cars, trucks, and light performance use.

Key practical perks include smooth pedal feel in cold starts down to everyday driving temps and steadfast protection up to 265°C dry boiling point - perfect for spirited road trips or towing without compromising safety. Shelf life stays strong for 3-5 years unopened when stored cool and dry.

When to Use / Replace?

Use RAP BRAKES R-LPH1 5.1 for routine maintenance or upgrades in modern ABS-equipped vehicles needing low-viscosity fluid for quick response. Replace every 2 years or 40,000 km, whichever comes first, as it absorbs moisture over time, dropping performance below 180°C wet boiling point and risking spongy brakes. Check fluid color - dark or cloudy means swap it now to avoid costly caliper or master cylinder damage.

• Ideal for passenger cars, SUVs, and track days under 200°C operating temps
• Flush system fully during brake jobs for max life
• Prevents corrosion in steel brake components

FAQ

Q: Is this fluid safe for my ABS brakes?
A: Yes, DOT 5.1 flows fast like DOT 4 but handles higher heat, ensuring ABS pulses correctly without air bubbles.

Q: How much for a full flush on most cars?
A: One 1L bottle covers small systems; grab two for larger trucks to fully purge old fluid.

Q: Can I mix with DOT 4?
A: Best to flush completely, but small top-ups are okay since both are glycol-based.
