I have found through trying myself and through orthers failures that at best, rebuilding wheel cylinders and especially master cylinders is a waste of time and at best a very temporary fix. Even the tiniest cylinder discoloration in the bore and it will not seal. Got to have the correct master cylinder and wheel cylinder combo and the master cylinder push rod adjustment at the correct spec. Brake adjustment, shoe to drum clearance, is critical with all the right springs in all the right places. Brake drums out of round will also present all kinds of problems including difficulty bleeding and difficult to adjust issues. Same with shoes that do not fit the drums. Shoe lining that does not fit the drum, hits on the ends of the friction material will be a problem and not only with adjustment; brakes will grab. With the brake adjustment cams on all four wheels cranked out fully, wheels won't turn, and difficult to bleed brakes will then join the program. This procedure helps where brake drum out of round is a problem and will help with bleeding only but will not help with a proper brake adjustment.HTH Warren Anderson Sedona,AZ hello fellow 300 nuts/enthusiasts i am having a brake problem with my C conv. i have replaced the master cyl,brake hoses,rebuilt wheel cyls,bled brakes,bled some more,bled some more,bled some more,etc.shoes were relined.
