Capping the brake lines
« on: November 21, 2004, 03:26:32 »
Gentlemen,

I will be removing the front calipers to do an overhaul. What is the best way to cap the brake lines? The calipers might be out of the car for about a week so a long-term capping solution is requested.

Thanks,

Juergen

I woild suggest you drain the entire system prior to removing the caliper and avoid the capping idea.  You will likely need to refill the entire system anyway.

On a related note, I bought a one man bleeding system for $40 recently.  Don't know why I put my wife through the brake bleeding torture for so long-this system is great!  Several companies make them.

Best,

Tom

If you put an air tight seal on the brake fluid resivoir, would that keep the fluid from draining because of the vacuum?

A trick I have used for years is  - Don't throw out those old swollen brake hoses ..
 I just cut the hose a couple of inches from the fitting end and stick the right size nail/rivet in the hose .. Then , whenever doing brake work, you have a screw-on stopper with the correct fitting to screw on the line you want plugged......
 Cheap tool ..just throw them in the tool box instead of in the trash.........

I use golf tee's to block the lines with good results. You may want to flush the master cylinder and lines with 99% isoproponal alcohol when you take it apart and then upon reassembly flush out the alcohol with brake fluid. Don't use type 5 silicone brake fluid in these older systems not designed for it. Brake fluid should be changed at a regular interval just as your other fluids, depending on the conditions. I think at least every 5 years, and if you are in more severe usage such as water or high heat even more.

I like the idea with the old hoses. Too bad mine were replaced this summer and the old ones were tossed... MB Cylinder and all lines are new, so is the fluid, hence my desire to get away hassle-free this time and just plug the line - well, gotta go look for those golf tees.

Thanks,

Juergen
