    Q:
    How to remove the Brake Calipers for overhaul on Chevrolet Astro? Posted by Maggie K.
    A:
    To get started with the removal of brake caliper for overhaul, open the brake fluid reservoir and check its level if needed. Then, loosen wheel lug nuts, jack up a vehicle as well as remove the wheels. After that, bottom the piston in the caliper bore and clean it before any hose is disconnected. Lastly, take out mounting bolts and separate caliper from automobile. The replacement will start by taking off brake pads and cleaning outside of calipers. While removing pistons from calipers using compressed air be cautious not to damage them. Take out dust boot and piston seal throwing away any rubber parts. All components are washed and reviewed for possible damages on both piston as well as caliper bore lineages. Lubricate piston bores along with seals then assemble caliper using new bushings plus sleeves For fitting purposes confirm availability of mounting bolts while pushing back piston into its bore where required Place caliper over rotor together with mounting bracket then tighten bolts after checking clearance Install brake hose while bleeding brakes Ditto; finally install wheels lower vehicle and pump brake pedal ensuring contact between pads & rotor.
