Forgive me if this has been posted somewhere. I’ve looked everywhere for any info on this. 1998 Silverado, Z-71. 400K miles +/-... Just replaced ALL brake lines, calipers, upgraded master cylinder to 2001. Brakes have been awesome for several hundred miles. Passenger rear wheel cylinder keeps blowing front piston out suddenly. E-brake cable has been inop and tied off to the frame for years. Could this have moved inside the drum assembly causing too much room for the piston to extend? Both pistons do not touch the brake shoes at he same time when adjusted as tight as I can get them and still get the drum on. I believe all parts are correct. Can I just remove the brake cable from the ebrake inside the drum and leave it off? Haven’t used it in 15 years, so pretty sure I wouldn’t miss it. Thanks for any thoughts on this - other than I will die a fiery death after going over a cliff on Dead Man’s curve if I were to not have a functional emergency brake - you know who you are ha ha!
