The new front wheel cylinder I installed 2 years ago is weeping. Defective part (NAPA), or faulty installation procedure (first attempt)? Can anyone offer tips so I can be sure to do the next one right? Time to change fluid and bleed anyway. Aside from doing the swap in a bucket of brake fluid, what's the best way to keep air out of the system? I should likely change fluid & bleed entire system BEFORE the swap, to minimize any crud getting to the new cylinder?
