keithb7 Posted August 25 Report Posted August 25 The car’s winter hibernation. A wheel cylinder will usually start leaking at some point. They don’t like to sit. This year I tried something different before going into a wheel cylinder. I removed my master cylinder cap. I used a pipe thread fitting and adapted it down to a hose barb fitting. I pushed a hose on it I pulled 20 in/Hg vacuum with my hand pump. The vacuum held solid. I popped open my wheel cylinder, disassembled and cleaned everything up. The fluid in the master held nicely while I serviced the brake. Only 1 brake to bleed! No dripping master while I worked. The plan worked well. I’ll do that going forward, when going into a brake. 3 1 Quote

keithb7 Posted August 25 Author Report Posted August 25 Dry threads would not seal. Teflon thread tape sealed everything up very well. 1 Quote
keithb7 Posted August 25 Author Report Posted August 25 Now I’m thinking, if I use a 30” or so clear piece of line I can also use this fitting to top up my master cylinder. Its a PITA to get brake fluid in it. I use a small syringe. Next time I’ll try this idea too. Quote

JBNeal Posted August 25 Report Posted August 25 if'n you're running with DOT 3, shouldn't that be flushed every 3 years or so? Quote
