I’ve replaced the front 2 wheel cylinders and rebuilt the rear 2 as well as rebuilt the master cylinder. I’m scared to mess with the hydrovac. Should I pull the unit off and disassemble and clean/inspect? The cylinders have all been a mess. I’m guessing the hydrovac is going to be dirty too. Suggestions? | | | | | Joined: Dec 2015 Posts: 2,062 Big Bolt Forum Moderator | | Big Bolt Forum Moderator Joined: Dec 2015 Posts: 2,062 | It is probably best to pull it apart. That being said, I did everything but that on my 58, (including all the steel and rubber lines) and mine has been just fine. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | |
