Roger Chatfield 0 Posted February 27, 2016 Evening chums, I've just repaired and refitted my abs unit, all is working ok but it does need a bleed. I've got a pressure bleeder, so what the best routine, do the calipers first or do the abs unit first? Rog. Quote Share this post Link to post Share on other sites
robrado974 1 Posted February 27, 2016 Calipers first Rog . Then if you still have a problem like I did, move on to the pump and the master . Quote Share this post Link to post Share on other sites
seanl82 23 Posted February 27, 2016 It's a pain in the arse Rog! I put 4 litres through it the other week and still wasn't happy. Paid a garage to do it and Mot it, but it came back exactly the same as before, but with a fresh ticket. Think it may have been because I'd been driving the Bimmer for a while but I could have sworn they were better before! Quote Share this post Link to post Share on other sites
fla 9 Posted February 27, 2016 In my experience it does take a good few miles after bleeding to get a proper feel back. In the meantime I just press the brakes a bit sooner and use the gears slightly if really necessary. Quote Share this post Link to post Share on other sites

Sean_Jaymo 0 Posted February 28, 2016 Easily the worst job on these cars. The whole system is just so finicky. Quote Share this post Link to post Share on other sites

Roger Chatfield 0 Posted February 28, 2016 Dry joint mate, mine only failed when it was cold so I assumed a dry that was closing up with heat. I just scraped the laquar off and resolve red each joint, took about ten mins, refitted and it now works fine. Just need to bleed the lines now, I've got a pressure bleeder so I'm hoping it'll go fine. Once that's done she'll be up for sale... :( Rog. Quote Share this post Link to post Share on other sites

My original pump was worse when cold, lots of inlet / outlet valve codes so I presume the issue is the power supply side affecting all within? Quote Share this post Link to post Share on other sites
