Description

What Is Brake Bleeding & Why It’s Needed Brakes in most cars work hydraulically: when you press the pedal, brake fluid transfers force from the master cylinder to the brake calipers or wheel cylinders. If there is air trapped in the brake lines or components, the system becomes less effective because air compresses (fluid doesn’t). This can lead to a soft or spongy pedal, delayed braking response, or loss of braking performance. Over time, brake fluid can degrade (absorb moisture etc.), or servicing (like replacing brake components) may introduce air. Bleeding removes the air and ensures the fluid path is all hydraulic fluid. What the Service Usually Includes / Steps Here’s what would typically be done during a brake bleeding service: Step What Technician Does Why It Matters 1. Inspect brake fluid condition & level Check the master cylinder fluid reservoir; note if fluid is dirty, low, or old. If fluid is old or contaminated, might replace it. Also ensures system doesn’t suck air in during bleeding. 2. Select correct brake fluid Use fluid matching vehicle-manufacturer spec (DOT rating etc.). Using wrong type can damage seals, reduce performance. 3. Prepare car Park on level ground, lift wheels if needed to access calipers/bleeder screws; remove wheels if required. Access to bleeder screws and safe operation. 4. Identify bleeder valves/screws On each caliper / wheel cylinder (for drum brakes), there are bleed screws. Find them and clean or loosen if required. Dirty or seized screws can cause leaks or incomplete bleeding. 5. Start bleeding sequence Usually begin with the wheel farthest from the master cylinder, then progressively to the closest. E.g. rear passenger side → rear driver side → front passenger side → front driver side (or as per car’s manual). 6. Bleeding process proper • Attach a transparent tube to the bleeder valve, with the other end into a container to catch fluid. • Have an assistant press the brake pedal (pump it a few times) then hold it down. • Open bleeder screw slightly, letting fluid + air bubbles flow out. • Close the screw before the pedal is released. • Repeat until fluid coming out is clear and without bubbles. • Keep topping up the master cylinder reservoir so it never runs low. 7. Final checks After bleeding all wheels, check pedal feel (should be firm, no sponginess), check for leaks at bleed points, inspect fluid level in reservoir, test drive gently to confirm braking behavior. Ensures the system is sealed, working safely, no further air in the system. What Auto Technix Should Do In Their Brake Bleeding Service Based on what they offer (brake repairs, fluid checks etc.), here’s what you can expect specifically if you take your car to Auto Technix, Andheri: They will likely use good quality brake fluid and ensure it matches your vehicle’s specs. They will bleed air from all four wheels (or only from the parts they have worked on if you had disc / caliper / hose work) to restore full hydraulics. They will check the pedals after bleeding and possibly test drive to ensure braking response is restored. They may also inspect related parts (brake lines, calipers, master cylinder, ABS unit if any) to see if there are leaks or other issues causing air intake. They’ll keep fluid reservoir topped during the service to prevent new air getting in. They’ll clean and tighten all bleed screws, and ensure everything is reassembled properly. Things to Ask / Confirm When You Avail This Service To ensure you get proper value, you might want to ask the following at Auto Technix: What type/grade of brake fluid they will use (DOT-3, DOT-4, etc.). Whether they will bleed all four wheels or only certain ones. Whether they include inspecting or replacing any leaking hoses, worn calipers, or other parts that might be admitting air. How they ensure no air remains (i.e. how many cycles of bleeding). Cost and time estimate. After-service checks (test drive, pedal feel).
