1993 GMC C1500 do I need to bleed each tire after I bench b

Hi there,

Yes, you must re bleed all the brakes, as air has now entered the brake lines, bleed rear first, normally working furthest from the master cylinder, make sure that the master stays at least 1/4 full while bleeding as if it empties the reservoir you will have to start over again.
