Left rear brake distribution block, one time use? (Read 2506 times)

Can it be re-used or should it be replaced?  Does the fitting (brass) conform to the connection and should not be used again?

It can be used again as long as it doesn't leak..I assume you are talking about break lines.

At work we routinely recommend replacement as best option.  However, in cases when replacements are not readily available or customer wants to avoid replacing them, we have reused some.

It is important to carefully clean the ports with solvent, small brush, and compressed air. 
Then closely inspect the cone shaped seat in the ports for any damage, even slight damage can cause leaking problems.  Most common type damage to the seat is from a previous crush ring which was off-centered.  Even after cleaning if the seats look bad it is highly recommended to replace.

Yes, I'm talking about the brake lines.  I was told that the distribution block is made of brass and that the nut on the hose/hard line will seat into the brass and thus make it a one time use item.  I'm replacing from the LR dist. block (new rubber hose, hard line and caliper).  I'll re-use it and check for leaks.

I've replaced break lines on many cars & have only replaced the blocks when they seem damaged. Always check for leaks after everything is done & you stood on the pedal.

I removed all my lined and the blocks and it just needed a good cleaning. Put it all back on and no leaks.

I'm about to undertake replacing the proportioning valve and all the rear break lines & blocks.

All 4 calipers and flex lines have been previously replaced, as has the front break lines, and master cylinder!

Is there anything unusual I have to worry about replacing the long break line going to the rear axle, crossover, blocks etc.

Any guidance would be appreciated. Will be working on a lift, so it shouldn't be a problem. I hope!!

Cover the ends of your lines with tape, rubber bands etc to keep dirt out. The cross over in the frt is tricky & the long one going back. Just take your time & you'll get-her-done. I was lucky I had the engine out to replace the frt cross over line. One of the safest & best things you can do to these cars. Are you going stainless lines?
