paddy Posted August 21, 2015 Share Posted August 21, 2015 Right just took my rear caliper off, new seals and a good clean up, I've put it back on, given every nipple a good bleed and my pedal feels crap, it does stop but it goes to the floor, the only thing I can think is when the brake pipe was off a lot of fluid came out, does it just need more bleeding or is there something I'm missing?

H_D Posted August 21, 2015 Share Posted August 21, 2015 I had the same problem not long ago - bleed it with the car running on idle. but its always best to bleed all 4 together starting from the furthest away from the master cylinder Quote Link to post Share on other sites
paddy Posted August 21, 2015 Author Share Posted August 21, 2015 Didn't think of that, pedal seems ok while not running, cheers Quote Link to post Share on other sites
StuDoc 72 Posted August 21, 2015 Share Posted August 21, 2015 You top up the reservoir? Have you checked its not still leaking? Quote Link to post Share on other sites
paddy Posted August 21, 2015 Author Share Posted August 21, 2015 Just tried it but no joy pedal feels the same, how much bleeding did yours take? I've done at 4, 3 times now Quote Link to post Share on other sites
paddy Posted August 21, 2015 Author Share Posted August 21, 2015 Yea resoviour has plenty in it, been keeping a close eye on it, I'm using 5.1 Toyota fuild which I recently changed. And no it's not leaking anywhere Quote Link to post Share on other sites
Broony Posted August 21, 2015 Share Posted August 21, 2015 sounds like air in the system start from the rear left, rear right, front left and front right Quote Link to post Share on other sites
daniel_g Posted August 22, 2015 Share Posted August 22, 2015 Pump the pedal till you get a bit of pressure and hold it down, get someone to crack the nipples off 1 by 1 (whilst keeping pressure on the pedal) and it'll hope push the air out. Quote Link to post Share on other sites
paddy Posted August 22, 2015 Author Share Posted August 22, 2015 Don't think there's any leaks, it was fine till the caliper went back on, I've bled it all loads of times now no air bubbles at all, master cylinder? Quote Link to post Share on other sites
JDMfreak Posted August 22, 2015 Share Posted August 22, 2015 check the master cylinder in engine bay I did one today the gasket between it and servo was gone pulled it of doubled up gasket small bit of blue sealant back onbled brakes rear passenger side 1strear driver side 2ndfront passenger side 3rdfront drivers side 4th got all air out and flushed all new brake fluid through brakes were grand again Quote Link to post Share on other sites
paddy Posted August 23, 2015 Author Share Posted August 23, 2015 I'm thinking it must be the master cylinder there's no air at all coming out the bleed nipples, is there any way of bleeding the master cylinder? When the brake pipe was off the caliper I had a big puddle of fluid on the floor after, think this may have caused my problem, I've been bleeding the calipers in the right order, had it running and not running, tried a Mitty vac, tried putting as much pressure as possible on the pedal.... Still feels the same, just fitted a td04 with a LSD box, last thing I need is shit breaks lol Quote Link to post Share on other sites
paddy Posted August 23, 2015 Author Share Posted August 23, 2015 It was all completely fine till the caliper came off, I've been told maybe that because I attached and tested my handbrake before putting the brake pipe back on the caliper this may have left a pocket of air in the caliper? Has anyone ever heard of this? Quote Link to post Share on other sites
paddy Posted August 23, 2015 Author Share Posted August 23, 2015 Just a thought but my abs is unplugged, could this make any difference? Maybe I got air in it? Can it be bled? Quote Link to post Share on other sites
jellybaby Posted August 24, 2015 Share Posted August 24, 2015 why is it unplugged ??? broken ??? if so remove the whole lot get a delete kit and u be right a rain Quote Link to post Share on other sites
StuDoc 72 Posted August 24, 2015 Share Posted August 24, 2015 Make sure all connections are sealed. Top up reservoir with fluid. Get someone to sit in the car and pump the pedal. Once they have pressure, hold pedal on and crack the furthest away bleed nipple being the n/s/r, fluid will shoot out and pedal will hit the floor. With pedal still depressed. Tighten bleed nipple to prevent air being drawn back in. Pump again until pressure and hold pedal on...crack nipple. Repeat this multiple times at every caliper going n/s/r - o/s/r - n/s/f - o/s/f being sure to top up fluid as you go. Until fluid flows from each nipple steadily with no air bubbles. Once this is done you have a fully bled system with no chance of air. How many times can you say nipple in one post Quote Link to post Share on other sites
Ollieh17 Posted August 24, 2015 Share Posted August 24, 2015 By a bleeding kit from halfords, cheap and makes life alot easier. Dont have to keep opening and shutting the nipple Quote Link to post Share on other sites
Garmstrong Posted August 24, 2015 Share Posted August 24, 2015 I had this the first time I ever bled brakes, replacing a caliper actually, turns out the seal in the master cylinder had flipped ! Garage used the pressure bleeders that go on top of the master cylinder and it solved it. Sure Halfords sell em for 50odd quid.Hope you sort it. Quote Link to post Share on other sites
paddy Posted August 25, 2015 Author Share Posted August 25, 2015 why is it unplugged ??? broken ??? if so remove the whole lot get a delete kit and u be right a rain As it cuts in far to early for what I like Quote Link to post Share on other sites
paddy Posted August 25, 2015 Author Share Posted August 25, 2015 I've got a Mitty vac which sucks out the fluid through the nipple, I've bled it all loads of times now I've lost track, the brakes feel ok but defo not as the were, I'm gonna put a new master cylinder in it and try again, I think I've gone wrong by not clamping the pipe while I took the caliper off, think master cylinder is all it could be, tried everything now Quote Link to post Share on other sites
