  Q: What steps should be taken before overhauling the brake master cylinder on Chevrolet Tracker?

  A: To decide if you should repair the brake master cylinder, find out how easy it is to get hand-built or brand-new brake master cylinders and brake master cylinder rebuild kits, along with their prices. The brake master cylinder sits in the engine area, fixed onto the power Brake Booster. Suck out as much liquid as you can from the tank with a needle and syringe. Put old rags underneath the brake fluid's connection points and get caps or plastic bags ready to cover the ends of the lines when you disconnect them, being careful because brake fluid could damage your vehicle's paintwork. Wear a flare nut wrench to carefully loosen the end nuts on the Brake Lines entering the brake master cylinder, stopping this from deforming the nuts. Keep the brake lines away from the brake master cylinder while plugging their ends to keep dirt and moisture out. Unplug the electrical wire from the brake master cylinder. Then, unscrew the two nuts that hold the brake master cylinder to the power booster and pull the cylinder off the studs, but keep it from dropping inside the engine room. Handle with care to avoid fluid spillage. To begin the rebuild, first buy the complete replacement parts kit and follow all included steps. Check if there's a base leak by looking at the grommets in the reservoir area. When you notice problems there, remove them from its place. Secure the cylinder in a vise, and push down on two pistons until they hit the cylinder's bottom, then hold them and remove the memo screw from the side. While holding each piston in place, take off the snap-ring on the brake master cylinder's end using care, then carefully pick out the inner brake parts from the cylinder's tube remembering the components' correct order. Look inside the brake master cylinder's bore for deep cuts or damage that demands replacing the entire brake master cylinder. Follow rebuild kit instructions to install all necessary parts. Clean parts you reuse with brake fluid that's brake clean or alcohol-based, but stay away from petroleum cleaning products. Pull all brake fluid components into the assembly hole, soak them well in clean brake fluid, then push them into the bore until they rest against the end of the cylinder. Secure the final part with a new gasket and stop screw. Place the new ring correctly inside its place on the groove. Fill the reservoir while putting your brake master cylinder in a vice grip. Insert threaded plugs into the brake line outlets before installation. Grip the piston assembly and remove a plug. While keeping pressure, put the piston into the brake master cylinder bore. After air comes out, replace the plug before lifting the pressure. Fill up the reservoir with brake fluid while pushing the piston each time until nothing but brake fluid comes out from the outlet hole. Keep refilling so air can't enter the system. You can seal the hole with your finger instead of plugging it while you're bleeding the brakes. Loosely attach the brake master cylinder to the brake booster studs first. Hold the nipple connectors onto the brake master cylinder tubes and connect them to the power brake booster loosely. Place the end of each metal brake tube into the brake master cylinder's port, then move the brake master cylinder gently to help guide the tubes, before bolting the tube ends securely with nuts tightened to their required torque setting. Begin by refilling the brake fluid container that fits inside the brake master cylinder, then make sure all trapped air escapes the brake lines during assembly. An assistant will hold the brake pedal in position while you take off the fitting screw, gradually letting air and fluid flow out until the liquid runs clear. Continue this procedure until the brake master cylinder works properly, then check your brake system before putting the vehicle back into regular road use.
