Master cylinder clutch line

[Jackrabbit41]

So at the sand dunes my 2 month old clutch line blew a hole in itself. The line that connects the master to the slave. Anybody know why? Totally random? My uncle thinks that I should get a stainless braided line crimped on their instead.

Materials defect? Could also have been damaged in handling, gotten a small tear in it by kinking or contact that quickly wore through. Doesn't take much. Something under that much pressure either holds it or it doesn't... once it starts leaking it blows itself right out.

Too close to the exhaust manifold. Sand dunes ==> engine works hard, manifolds get very hot, slow speed, no air circulation to cool the line.

Should I get a stainless line?

Should I get a stainless line?

Can't hurt. But the line itself is still rubber -- it just has a stainless braid around it for reinforcement. Heat will still kill a stainless line. You need to make certain it's routed well clear of the exhaust manifold, and if you're going to do much dune riding you might consider wrapping it with a foil insulation of some type.

Just don't buy the Dorman line off of Rockauto. Worst 25$ I ever spent... immediately had a massive leak where it connected to the master cylinder.

I'd do a braided replacement.

 

FWIW, the factory used the wrong brake fluid on the assembly line and it ate up the inside of the hoses. This caused debris from that to get into the master and slave cylinders and ruin them. We were told to replace master, slave, and hose all together and use Castrol GT

LMA fluid as the cylinders were British.
