Dylanfarrell Posted July 13, 2014 Share Posted July 13, 2014 (edited) Okay so, I've fit my BZG brakes, discs and pads. I fully retracted the pistons before fitting. Made sure the MC was completely topped up, cleared the bleed nipples with the compressor and applied grease to threads to ensure tight seal, clamped lines before refitting. Lid left on MC and engine off. Copper washers replaced and everything on tight as I could manage Started by opening front passo side and pumped with the nipple open for a minute into a jar of fluid to pass as much air as I could first. Did the same for driver side then. Once I got a bit of a feel in the pedal I bled both the fronts ensuring fluid stayed topped up. Problem is now once the car starts up all feel is gone from pedal and takes 3 pumps to stop the car. I then went on to bleed all the brakes from furthest from the MC to the closest and it improved some but still takes 2 or 3 pumps to stop. Any suggestions as to the issue??

Jamie5414 Posted July 13, 2014 Share Posted July 13, 2014 (edited) take all wheels off, take cap off brake fluid res. start car, get someone to keep applying the brake on command get a hose and a cup part full of brake fluid, attach to passenger side rear bleed nipple, loosen and get person to pump break till it's clear. tighten nipple again on driver side rear, again on driver side front, again on passenger side front. keep topping up brake fluid res. (you may need to do the cycle twice to make sure they are bled correctly, i've had a lot of air come out when doing it a second time so best to do it twice, if not three times) it still takes 2-3 pumps after this process? it should be stopping with the first push on the brake Edited July 13, 2014 by Jamie5414 Quote Link to post Share on other sites

From reading and being told by others they all say to leave the car off during bleeding? Could this be the culprit? As I've followed pretty much everything you've said there to a tee more than once and every time there's been nothing but clear brake fluid coming from the tube Quote Link to post Share on other sites
Jamie5414 Posted July 13, 2014 Share Posted July 13, 2014 i've always done it with the engine on and pumped it with it running, never done it without, maybe it can be done without the engine on and just ignition on, but as I say I just do it with the engine on, the person inside can keep warm with the heaters on then lol Quote Link to post Share on other sites
morgey Posted July 13, 2014 Share Posted July 13, 2014 I've never done it with it running. or even with the key in it. id just go around again and double check you havent got a leak. Quote Link to post Share on other sites
Dylanfarrell Posted July 13, 2014 Author Share Posted July 13, 2014 So went and tried everything. Bled from back corner all the way around again. Covered the MC with a but of plastic to get a better seal and still no dirt or bubbles from the caliper. Bled the MC in situ and still nothing. Hardly to do with the smaller N/A brake servo being up to pushing enough fluid for the BZG brakes? Quote Link to post Share on other sites
Dylanfarrell Posted July 15, 2014 Author Share Posted July 15, 2014 Definitely one of those palm to face moments but all the answers are in here! DOH!!!! http://www.ukstarletowners.com/topic/65139-no-brake-pedal-hits-floor/ Quote Link to post Share on other sites
morgey Posted July 15, 2014 Share Posted July 15, 2014 Calipers on the wrong side so upside down? Hahaha classic ill have to remember that one.Tbh next time you have an issue. Post some pics someone would have spotted that in an instant ;) Quote Link to post Share on other sites

Post some pics someone would have spotted that in an instant ;)I know, luckily I was fortunate enough as to not have to go through so much work to come to the same conclusion. Swapped around, quick bleed and they were rock solid! I was really blindsided by the fact that they bolted on as they should and looked spot on only for the bleed nipple was pointed down as opposed to up! Quote Link to post Share on other sites
morgey Posted July 15, 2014 Share Posted July 15, 2014 Least you got it sorted thats the main thing! Quote Link to post Share on other sites
Dylanfarrell Posted July 15, 2014 Author Share Posted July 15, 2014 Exactly, now just to take the most of it off again and replace the CV boots haha getting a bit too efficient at dismantling my front end Quote Link to post Share on other sites
morgey Posted July 15, 2014 Share Posted July 15, 2014 You should get away with just undoing the shock bolts and the bracket for the brake line to get the driveshaft out the hub Quote Link to post Share on other sites
Dylanfarrell Posted July 15, 2014 Author Share Posted July 15, 2014 I was hoping to get away with that alright, works for most yokes I've worked on before. Turns out my friend has been having the very same problem with his brakes after having the whole car apart. Thought the MC and Abs were air locked. .... turns out he also put the calipers on back wards too lol Quote Link to post Share on other sites
Amjad Posted July 20, 2014 Share Posted July 20, 2014 I've been advised to to do them with engine running too Quote Link to post Share on other sites
Dylanfarrell Posted July 20, 2014 Author Share Posted July 20, 2014 I've been advised to to do them with engine running tooDid it with the engine off and it worked flawlessly, ran clear pipes from calipers to jars with some fluid. Pumped with valves open a few times, tightened up and pedal was rock solid. Quote Link to post Share on other sites
