Here is the DOT-3 question: I just finished the brakes, front disks (new seals), rear cylinders replaced with new units, master cylinder new seals. All lines did not apear to have any leakage. I installed the master cylinder (after bench bleeding) and filled it about 3/4 full. The brakes have not been bled yet and all bleeder valves are closed and tight.
I decided to run the motor for a while (15 minutes) and do some timeing, and carb adjustments. After turning off the engine, I checked the master cylinder and it was down by 1/2 of the fluid.
Based on the age of the vehicle, and having been stored for 18+ years, I was hopeing the booster might still be good. Is it the opinion of this forum that the break fluid was vacuumed into the motor?
Is there a way to check to see if the brake fluid is going into the vacuum while the motor is running? I pulled the vacuum line off expecting to see wetness, but things were dry.
Thanks, I'm Havinfun.
