This may be kind of a noob question, but I'm trying to remove my BMC, and I can not for the life of me get thee brake lines off of the underside of the cylinder. Should I be trying to get the check valves off too?

It's a 1980 ZX NA and FSM has been of no help so far.

 

Welcome to Zdriver man. As for the brake lines. You need a brake line wrench. It will be 10mm I think. I just bought one a short while back. Do not use a regular wrench on the lines. You will round off the nuts. Then you just have the 2 12mm nuts, and the master cylinder should come off. Along with the plate, that holds your heat shield on. Hope that helps, and good luck.

 

Thanks, I'll pick one up tomorrow. Heat shield and 12mm weren't a problem, but just like you said, these ones just round right off.

 

if you can't get it off with a tubing wrench use vise grips.

i wouldnt use a vise grip unless you plan on redoing the fitting.

 

Yeah, vice grips are a no-go. Nowhere in town has a tube wrench. Sears, Lowes, all local hardware store are sold out and NAPA and O'Reilly only have sizes down to 11mm in stock. Looks like I'll be ordering online..

 

****, everyone is buying up all the brake line wrenches?

Order me a few, I need like 6, just in case.
