Mike 1948 1Ton Posted May 7, 2018 Report Share Posted May 7, 2018 Woke the truck up from storage, no puddles under the truck. Whet to get gas and beer, about 10 mile round trip. Parked in garage and see a puddle on the floor under the master cylinder, leaking from the rear boot where the plunger shaft goes in. Bad seal? I have the rebuild kit on hand. Does the cylinder need to be honed when I get it out? thanks Mike Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted May 7, 2018 Report Share Posted May 7, 2018 Rebuild or replace depending on how it looks inside . Some of us are having the old master cylinders sleeved with brass or stainless steel so that the next time it happens you can just pop in a kit .

Mike 1948 1Ton Posted May 7, 2018 Author Report Share Posted May 7, 2018 Good point, I'll have to see what it looks like when I get it out. Thanks Quote Link to comment Share on other sites More sharing options...
Young Ed Posted May 7, 2018 Report Share Posted May 7, 2018 If you want to have it sleeved brake and equipment warehouse in NE can do it. Quote Link to comment Share on other sites More sharing options...

Mike 1948 1Ton Posted May 14, 2018 Author Report Share Posted May 14, 2018 (edited) Here's the problem, line coming out of the back/bottom of the master cylinder. The crack was facing straight down. Was not leaking over winter, but must have had a bit of water around the fitting? I remember that the road was wet and muddy the last day I drove it last fall. So maybe a small bit of water settled there and froze. Then the first time I drive it this year it let loose. While I have it all out I am going to put the new parts inside the MC, spring, cup, piston and all the other little stuff in there. Should be back to normal soon!

Mike 1948 1Ton Posted May 15, 2018 Author Report Share Posted May 15, 2018 Good point, I will do a closer look at the lines to see if there is more copper. This little line actually goes to the brake lock solenoid (which doesn't work) so I think this could be the only copper piece (I hope). Thanks for the comments!!!
