400BHP Posted June 18, 2003 Share Posted June 18, 2003 you could always go one step further and evac the system with an air pump then flush with meths, cleans out all the nasty oxidisation... Quote Link to comment Share on other sites More sharing options...
Doughie Posted June 19, 2003 Share Posted June 19, 2003 Originally posted by Keith C Removing the trac eh? Hmm, tempting. Tricky to do? I'd quite like to cermoniously burn mine Best not I guess - so just to be sure, by using traditional 'mate-in-car-with-foot-on-pedal' brake bleeding I don't need to fanny about with the trac system? Stu - can you remember when you had it done? yep Keith i'm 95% sure that the brake fluid was changed at the last service the car had shortly before you bought it. I think perhaps only a month or two before. I even took along 2 bottles of new DOT5.1-spec fluid with strict instructions for them to use that. higher spec than Toyota fluid (i think they use DOT4) and also ..... cheaper ! so it had new DOT5.1 fluid at the service shortly before you got it. cheers ps. what pads you running these days in it ? and did u change the discs ??

Keith C Posted June 19, 2003 Share Posted June 19, 2003 Yeah, new discs, and Chris's pads. Gonna put some Motul stuff in it I reckon. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted June 19, 2003 Share Posted June 19, 2003 the full system takes just under 2litres Is this a UK spec figure? I completely drained my system, changed calipers and flexi hoses then refilled with AP racing fluid and it took 1 litre, give or take a few mls.

Guest Martin F Posted June 19, 2003 Share Posted June 19, 2003 You are right, sorry about that. Just been out to the garage to check the size of my bottles and the're 500ml and i remembered using two. Thought they were 1l. Quote Link to comment Share on other sites More sharing options...
SkyJawa Posted December 23, 2003 Share Posted December 23, 2003 Ressurrect old thread time again So I take it on the Jspec theres none of this traction control malarky? I can just bleed as normal? Also, I'm gonna have to drain the system as I'm fitting braided lines at the same time as the UK calipers, is there anything to watch for since it will be all drained (other than make sure all air is out)????

fastphil666 Posted April 9, 2020 Share Posted April 9, 2020 I have rebuilt mh calipers recently (fronts) due to braided lines i clamped flat bar over the banjo end but it still weeped through and the system ran dry. Have tried bleeding a few times but still feel spongy and no feel until half way down. My jspec tt auto has trac and abs so i should follow the tecnique above?

Hissig Posted April 9, 2020 Share Posted April 9, 2020 congrats on crazy thread bump ! You have to bleed your master cylinder. easily done . disconnect the lines to the master cylinder/reservoir. have a helper press the brake pedal and hold it down, then block the two holes (where you disconnected the lines) with your fingers and have him release the pedal. Do this til you have no more air coming out. then bleed your brakes as usual. Quote Link to comment Share on other sites More sharing options...
fastphil666 Posted April 9, 2020 Share Posted April 9, 2020 Thanks for that i will have a go. I figured normal brake bleeding procedure would clear air out the m/c but i may be wrong. Quote Link to comment Share on other sites More sharing options...

fastphil666 Posted April 11, 2020 Share Posted April 11, 2020 Thanks dunk, ive seen the manuals being referred to a few times but couldnt find them. Didnt think to look on the main welcome page. Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 11, 2020 Share Posted April 11, 2020 (edited) Thanks dunk, ive seen the manuals being referred to a few times but couldnt find them. Didnt think to look on the main welcome page. No problem, when we replaced all my brake calipers and brake lines on my UK spec we bled the system using a Gunson vacuum bleader and had a great pedal straight away Edited April 11, 2020 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
fastphil666 Posted April 11, 2020 Share Posted April 11, 2020 I have an ez bleed but its a pump through the master cylinder type. Doesnt have a fitting for the supra either. Doh!! Anyways thsnks for the help folks, bled the master cylinder as per manual then all 4. Much better pedal, feels more progressive and bites hard around 1/2 travel rather than starting at half pedal. Only issue now ive found the m/c lid wont fit on properly one side always lifts up and can be lifted off with little effort. Have the oem part number 47230, just where to buy? Toyota only?
