Brake piping
 

I have changed all the brake piping on my track saxo for copper pipes.

I am running a single brake line to the rear with a bias valve in the middle. at the rear it splits at a T piece to each wheel.

I have a larger master cylinder and completely removed the abs system. I have changed the flexible pipes for braided.

On cadwell park a month or 2 ago I burst the nearside rear pipe where it comes out of the braided pipe.

I have re done this part again with new piping but less than a month later it has burst again in the same place. I don't feel that I have been braking heavily since I replaced the pipe as its only been used on the road.

What do people use instead of copper piping or can anybody notice an issue with my setup?

Thanks

Anyone??

flaring not quite right?
maybe try a different material of pipe like kunifer

Are you doing the right type of flare on the pipe?

Thanks for the reply, I will look into that material

I have seen a few saxos with braided lines throughout so was thinking that could also be an option, but I guess it could get quite expensive.

I believe so. I didn't actually do it myself, one of my mechanics did it, hes been a mechanic for over 35 years so I don't think he would get it wrong twice.

I'm thinking that it could be a cheap copper pipe that may have been stretched when flared.

I was just concerned that there was a fault with my setup and it was building up too much pressure at the nearside rear

buy some different pipe from another manufacturer and try that. To be honest i've never had copper pipe fail continually unless the flare was too small or the copper old and brittle and even then its leaked straight away rather than fail dramatically.

I have just ordered 25ft of kunifer nickel piping so I will get that fitted and see how it goes.

Copper in mine mate.

volvo have used copper on 240.s +740,s for 30 years+ and never a problem --so it must be a flare problem
or it is not secured correctly and vibrating and cracking it ?
breaking right at flare ?-- then you have your answer
