brake peddle almost hitting floor board

Asked by Jul 23, 2015 at 04:18 PM about the 1968 Chevrolet C/K 10

Question type: Maintenance & Repair

Replaced front brakes on 1968 Chev 1/2 ton pickup.  Bled all four lines as peddle was
almost hitting floorboard before and fluid was low in master cyl.  Still have very low brake
peddle.  Do I need to  bleed the lines more?  Maybe master cyll needs replaced?  Brake
linkage seems tight.  No evidence of leakage anywhere.

Look behind wheels make sure its not leaking out from a bad wheel cylinder if its not leaking bleed out line see if pedal comes back

1968 did have auto adjusters on all 4 brakes, they could be froze so they won't adjust properly. Remove the brake drums and see if the adjusters will move and operate properly.

If the lines to the breaks are clear of air and you see no fluid leaking anywhere at the break cylinders or in the lines and you can not "pump" the breaks to a firm condition, then the next suspect is the "O" rings on the master cylinder. Another culprit can be the vacuum assist drum with a leak in the drum itself or a bad check valve where the vacuum line attaches to the drum.
