I lost my brakes today and of course I am 350 miles from home.

First thing I checked we the fluid level and all there was in there was rust. I made it to a parts store and got a bottle of fluid and filled it up and I can pump them up enough for this weekend and then tow it home behind my motorhome.

what are some good replacement brand or ones to stay away from. I does have SS lines already but the fluid looks like hot chocolate after pumping the brakes up I will have to flush all the lines.

I replaced mine in 1998 with a Napa master cylinder and I'm still using it.

Has anyone had to flush their brake system?

after I put brake fluid in and drove it the fluid looks like chocolate milk.

If you have how did you do it, just pull fresh fluid through unit it comes out clear?

The cleanest way to change the fluid would be with one of those brake bleeding tools where you can catch the fluid. If you don't mind the mess you could open the wheel cylinder valves and pump the brake pedal until you get all of the old fluid out.

I do have a mighty vac that would work IF I can get the bleeder valves open, if not I will have to pull the cylinder and probably cut the line off??

Worst case is vice grips on the bleeder if it strips with a wrench. Try using a line wrench, it can help minimize stripping. A trick I use on underbody bolts and nuts is to tap the wrench with a hammer, tightening direction first, then try and loosen it. PB Blaster ( or the like) can help too.

I'd never buy a remanufactured master cylinder again.

I purchased a new MC from Napa and recommend.

NMC M2506 (Manual Brakes)

NMC P2506 (Power Brakes)
