Weird brakes

I'm envious that you can get out and work on the ride when the rest of the east and midwest are hacking out of ice. IMO, start with the easy stuff first. Since you say you replaced a rear wheel cylinder, is it possible that there is a little air in the line?

The best cure is to bleed the system. You'll be doing this with a new master cylinder. Keep fluid coming out of the bleeder valve until you have a clear stream with no bubbles. Check MC frequently as it is not good if a reservoir goes dry. Use this for sequence. RR-LR-RF-LF (work from farthest out towards master cylinder.)

I can understand what you mean. My father is up in WV and wants to move down here to Florida. He has three feet of snow in his yard while I'm baking in 90 degree heat. I replaced both rear wheel cylinders, but it's been almost two months since I did that. I'm thinking the seals in them probably started leaking because I know the quality of stuff is kinda terrible anymore. Being it's dark out and I live in an apartment building, it's gonna have to wait until tomorrow since I have the day off. Tomorrow is going to be all about brakes because I'll be fixing this and putting new brakes on the wife's 2000 Jimmy, maybe even replace the rotors on my truck since they're full of grooves.
