Guest Darragh Posted January 26, 2006 i am currently helping a friend with his 205. it has Wilwood Midilight 4 pots with 285mm discs on the front and standard rear calipers with drilled and grooved discs. the master cylinder is 23.3mm from a 406 with 406 resevoir, using standard braded hose throughout. after numerous attempts trying to bleed the brakes we have still not managed to get rid of all the air in the system. an air lock in the master cylinder might be the problem but we are not sure how to overcome this problem. any ideas, comments and useful hints would be much apreciated..... regards Darragh Share this post Link to post Share on other sites
C_W 3 1 Cars Posted January 26, 2006 I always use a Gunson's Easibleed now with uses air pressure from a tyre to force the fluid through the system and is easy to do on your own without the silly open bleed screw "pedal down", "pedal up" routine. Some people have problems securing the pressurised cap on the reservoir but it fits the 406 one fine and tight (its not very good with the standard reservoir though).

pug_ham 244 3 Cars Posted January 27, 2006 wheres the best place to buy one from C_W?Any car spares stockists imo, Motosave, Motorworld, Halfrauds etc. I got mine from my local motor factors iirc. Graham. Share this post Link to post Share on other sites
M3Evo 0 Posted January 27, 2006 I'm having some probs with Wilwood bleeding at the moment too, can't stand those easi-bleed things though. Only managed to get one to work properly once, other than that they always seem to piss fluid EVERYWHERE Quite tempted to buy one of those vacuum bleeding things, you attach it to the bleed nipple and draw the fluid through.

Dream Weaver 2 Posted January 27, 2006 Just did mine with an Easibleed, £15 from Halfords and worked a treat. As long as you get the cap to fit securely there are no issues. Share this post Link to post Share on other sites

As long as you get the cap to fit securely there are no issues. nice one!! i already tried with the easibleed and still more air comes out. i recon il cheack that all the unions are nice and tight. then try try again.

Try some PTFE around the thread? I hoooked mine up to a compressor so I could change the pressure easier, about 15psi I usually use. Share this post Link to post Share on other sites
C_W 3 1 Cars Posted January 27, 2006 I use 30psi(!) on mine, not recommended I know, but I'm happy the seal is fine (although I always put a load of rags over the reservoir just incase! Share this post Link to post Share on other sites
M3Evo 0 Posted January 27, 2006 Never really understood the pressure thing on the easi-bleed. Surely when you stamp on the pedal you get hundreds of psi in the system anyway? Or is it just to prevent the non pressurised seals rupturing? Anyway, £35 for a mityvac vacuum bleeder sounds good to me. Share this post Link to post Share on other sites

pug_ham 244 3 Cars Posted January 27, 2006 I use 30psi(!) on mineMe too but I also cover the engine bay with a plastic sheet & use a couple of cable ties to secure the cap onm the (standard) reservoir. Learn't the hard way after swapping a ca,belt & bleeding the brakes whilst it cooled after the initial run to check tension. New belt please. Graham. Share this post Link to post Share on other sites
veloce200 3 Posted January 28, 2006 if you did the bleed initially with the pedal and you still have air you probably have inverted the seals in the master cylinder. I use easibleed after this happened on a friends car. The stroke of the pedal is too long with bleed nipples undone and the seals fail so no matter what you cannot get the air out of the system.

I use easibleed after this happened on a friends car. The stroke of the pedal is too long with bleed nipples undone and the seals fail so no matter what you cannot get the air out of the system. yeah that was exactly my experience. I also found that an eazibleed on a 'slightly overinflated' (55psi iirc ) tyre was the only thing that would overcome some old 1.9 rear compensators that would otherwise have needed renewing.
