Hydraulic Brake Master Unit for Suzuki SUVs 🛑

This OE-spec hydraulic control unit (ref. 5110065JA1) is the heart of your brake system. It converts your foot pressure into precise hydraulic force, feeding the front and rear circuits so your vehicle stops straight, fast, and safely. If you want consistent pedal feel and factory braking performance, this is the part you rely on. 🔧

Why this part is needed

Without a healthy master unit, your brakes cannot build or hold pressure. It keeps both circuits balanced, prevents internal bypass, and supplies clean fluid from the reservoir to the lines. It’s essential for everyday driving and emergency stops. 🛡️

How it works

Inside are precision pistons, springs, and seals. When you press the pedal, the primary and secondary pistons push fluid through ports to each circuit. Seals maintain pressure, the reservoir compensates fluid volume, and return springs reset the pistons for the next stop. Compatible with ABS modulator flow and DOT 3/4 fluids. 💧

What happens if it’s broken

Symptoms include soft or sinking pedal, longer stopping distance, uneven braking, warning lamp, and external leaks near the booster. Internal seal failure can cause pressure loss without visible leaks—dangerous in panic braking. Replace at once if contaminated or corroded. ⚠️

Fitment and service tips

Direct-fit, OE bore size and ports for fast install. Bench-bleed before mounting, use fresh fluid, and torque lines to spec. Avoid mixing fluids and keep all connections clean. ✅
