station Posted October 26, 2014 Report Share Posted October 26, 2014 I bought the car with pads seized onto the discs - it took five of us to push it into the garage. The steel brake pipes were busted as were and leaking everywhere. The car had I changed the pads, new brake hoses and replaced all the pipes and unions with copper pipes.All the calipers work and are not seized, but the brakes are poor.Would this be related to the master cylinder - I have done the clutch master cylinder in the past on another car (disassembled and washed it out basically), as it was 'filthy'.To describe it, I used the starter to move into the garage, and it suddenly started and the brakes felt very soft stopping the jolt towards the wall, instead of biting or skidding.

importwarrior Posted October 26, 2014 Report Share Posted October 26, 2014 sounds like air in the system. double check the master cylinder. Link to comment Share on other sites More sharing options...
JohnnyWadd Posted October 26, 2014 Report Share Posted October 26, 2014 I am curious about these copper fittings as a brake line repair. Link to comment Share on other sites More sharing options...

station Posted October 27, 2014 Author Report Share Posted October 27, 2014 Copper pipe is used as replacement for the standard steel pipe. It's soft and flexible and doesn't corrode. I'm in the UK unfortunately! Link to comment Share on other sites More sharing options...
vbrad511 Posted October 27, 2014 Report Share Posted October 27, 2014 Does sound like air in the lines. You need to bleed more. I too would be cautious of copper brake line, for the reason of it being soft. I wouldn't trust my life with them. Link to comment Share on other sites More sharing options...
hippynerd Posted October 27, 2014 Report Share Posted October 27, 2014 I imagine that copper lines dont rust, and dont leave rust in your brake fluid. I would flush the lines with new fluid, and blead any air out. That might be good enough to get things working good enough. The brakes are really pretty easy on starions. You could easily remove and service all 4 callipers, flush and bleed the system in one day. You might want to get your rotors turned, and replace your front wheel bearings while you have it taken apart. Link to comment Share on other sites More sharing options...
station Posted October 27, 2014 Author Report Share Posted October 27, 2014 (edited) Oh yeah, I had to do the bleeding thing anyway as there was no fluid in them. I've since bled them twice and can only come to the leaking master cylinder conclusion. Copper pipe is better than steel, I think manufacturers use steel because it is cheap and it isn't flexible.

t hall Posted October 27, 2014 Report Share Posted October 27, 2014 Point.... These 'copper' lines are not just soft copper.... that would not work. There are nickel copper lines that are DOT approved. use your google fu to see what is acceptable.https://www.google.com/search?q=copper+brake+lines&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb Don't try 'regular' copper.. not worth the risk!! understand the differences!!

station Posted October 28, 2014 Author Report Share Posted October 28, 2014 I've been using them for about 20 years - they're 'softer' than steel, hence easier to bend than normal steel - they can be bent by hand, steel can not, but there's no way fluid could ever burst them.I don't know what you use in the US, nobody replaces rusted steel brake pipes with anything other than copper pipe. http://www.amazon.co.uk/BRAKE-COPPER-UNIONS-METRIC-FEMALE/dp/B00FLVNZPK/ref=sr_1_1?ie=UTF8&qid=1414485586&sr=8-1&keywords=brake+pipe Link to comment Share on other sites More sharing options...
