bencider Posted May 24, 2017 Share Posted May 24, 2017 I've searched this topic alot.. Before I did the work and after .. Can't seem to find the correct answer.. My clutch was working fine.. It used to stick when hot. So whilst I'm doing a ton of work on my car I thought best to change slave and the rubber line for a braided one. I have swapped the slave and line.. Bled the system as the manual states and I get no air bubbles so all good. Trouble is now the peddle on comes up half way.. Was perfectly fine before.. And appears the bleeding went well.. No air etc. So I'm a bit confused., unless this buggered the master in the process? Quote Link to comment Share on other sites More sharing options...

Ekona Posted May 24, 2017 Share Posted May 24, 2017 Could be two things: 1. You've not bled it enough. These things are an absolute bugger to do. 2. The master is gone. Mine was after I changed my slave, and given the cost of the job is in the labour it's why I tell everyone to change both slave and master at the same time.

Adrian@TORQEN Posted May 24, 2017 Share Posted May 24, 2017 Either not bled properly or the master cylinder is gone. The common practice is that when you replace the clutch and slave, you should replace the master cylinder as well as it will fail pretty soon on most occasions. If it deems to be the slave, we have these in stock, both Tilton and Wilwood ones: https://www.torqen.uk/174-ancillaries Quote Link to comment Share on other sites More sharing options...
bencider Posted May 24, 2017 Author Share Posted May 24, 2017 (edited) Hope it's not the slave adrian as I just got it from you haha.. Thanks chaps.. Haven't changed clutch.. Pretty annoying this is.... OK . Do you sell rebuild kits or do I need a new master cylinder Edited May 24, 2017 by bencider Quote Link to comment Share on other sites More sharing options...
Adrian@TORQEN Posted May 24, 2017 Share Posted May 24, 2017 We didn't have a slave failing yet and we sold hundreds, I doubt it's that. Try bleeding the clutch again first.

ZMANALEX Posted May 24, 2017 Share Posted May 24, 2017 Just bleed it properly and you should be okay. You will have 99 Slave failures to one Master failure. 1 Quote Link to comment Share on other sites More sharing options...
bencider Posted May 24, 2017 Author Share Posted May 24, 2017 What do you mean bleed it properly? I don't know n what else to do.. It's bled.. With no air. That I can see as per manual? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 24, 2017 Share Posted May 24, 2017 You will have an air lock so that is why you are struggling to release the air. Get some one to help you who knows what they are doing. Quote Link to comment Share on other sites More sharing options...
Olly350z Posted May 24, 2017 Share Posted May 24, 2017 These guys know what they're saying buddy, these cars are notoriously difficult to bleed, found that out myself the hard way. Have you adjusted the pedal movement? Doing this might allow you to bleed the system easier as its letting more fluid pass Quote Link to comment Share on other sites More sharing options...
bencider Posted May 24, 2017 Author Share Posted May 24, 2017 No not adjusted pedal. I'm not doubting the advice.. I'm just saying Im not getting any air.. I did when I started but the fluid is clear and bubble free.. So wondered what I'm doing wrong Quote Link to comment Share on other sites More sharing options...
Ewen@Clark Motorsport Posted May 24, 2017 Share Posted May 24, 2017 As Alex says its likely to be bleeding, very rare for a master cylinder to need replacing. Quote Link to comment Share on other sites More sharing options...
bencider Posted May 24, 2017 Author Share Posted May 24, 2017 I'll keep bleeding the system until I run out of fluid See what happens. Quote Link to comment Share on other sites More sharing options...
Midmonster Posted May 24, 2017 Share Posted May 24, 2017 (edited) Think my slave cylinder is on it's last leg's, had a p3 service only a few weeks ago and had the fluid changed 2weeks later it started to play up on me. Seeing as i intend to keep the zed for a few yrs i'm thinking of going for the heavy duty master cylinder and slave.

At the worst swop out the slave and the rubber hose for a braided one. Guess that when they changed the fluid they did not bleed properly.

Midmonster Posted May 24, 2017 Share Posted May 24, 2017 (edited) I will have a go at bleeding it myself a few times and see what happens. the fresh fluid has already turned brown again with in a few weeks, was going to just go for the slave/braided line but thought why not go the hole hog lol Edited May 25, 2017 by Midmonster Quote Link to comment Share on other sites More sharing options...
