Quick run down of my previous problems leading up to the last week..
00 Disco II 149k miles.
A couple of months ago I had the rear passenger hard line break/rust through along the frame under the drivers side rear passenger door. No brakes!
Had it towed to my local LR dealer, they repaired the line. Brakes seemed soft when leaving the dealer. Returned and informed the service manager that they were now softer than they had ever been. Tech takes the disco, comes back and gives the default "they're good for a disco". I explain that they were much firmer before the rupture. They re-bleed the system and send me on my way. Still too soft. I ask for another re-bleed, they take the disco back and bring it back feeling the same. Service manager assured me that they used "testbook"?? to bleed the system, blah blah blah.
I'm not a mechanic by any means, but PT was kind enough to talk me through bleeding the system myself, and I've had a great, firm pedal until last week.
We had some freezing rain one day that gave the abs and TC a really good work out. That day however, the brakes started acting up. It stops without a problem, but while sitting, the pedal fades down. I can pump the brakes and the pedal still fades. I've crawled underneath it and see no leaks, and the master is full.
Any ideas? This just started after the freezing rain caused the abs and tc to kick in, it's been fine since the dealer repair (and me bleeding the brakes) a couple of months ago.
