Scott Posted January 27, 2011 Share Posted January 27, 2011 Was the system empty? Did you bleed the master cylinder before trying the calipers? It's a bit messy btw so you will know if you did it Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 27, 2011 Share Posted January 27, 2011 Vaccum bleed is much better in my opinion as it just fits onto the bleed nipple, open bleed nipple and it draws the new fluid though leaving the master cylinder free to easily top up as you go. If the M/C was empty then that needs bleeding first Quote Link to comment Share on other sites More sharing options...
Guest moddy Posted January 27, 2011 Share Posted January 27, 2011 Hi Ulysees I had the exact same problem last year, after changing my brake lines for braided ones and after i fitted them the damn thing would not bleed. I gave up after 3 weeks and gave it to a garage who couldnt fix it and i took it to another and their mechanic called chris wilson and after advice given it was still the same. When the engine was off i had a solid pedal, when you keep your foot on the pedal and start the engine it went down to the floor but it did pump up slightly just enough for short journeys and brown trousers. I changed the Master cylinder, calipers all 4 and put my old rubber lines back on and it was still the same no difference at all. The problem was my BRAKE FLUID dot 5.1 i think it may of been the silicone one, cant remember exactly but it was a toyota branded one and when i put in dot 4 Eureka my brakes worked. If you do nothing else change your fluid asap Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted January 27, 2011 Share Posted January 27, 2011 I read the earlier post to suggest I worked for whoever they are and I couldn't fix it. I would just have given advice over the phone, I work for myself (and 'er indoors, the taxman et cetera, but not another garage) Cheers. If someone had put DOT 5 fluid in, which is silicone, it could well have not been to the ABS units liking at all. Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 27, 2011 Author Share Posted January 27, 2011 The garage flushed the dot 5.1 out anyway and replaced it with dot 4. Im starting to think that its air in the ABS unit? how do you bleed that? Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 27, 2011 Author Share Posted January 27, 2011 We did my mates mr2 at the weekend and had a simular problem, we had air in the master cylinder itself so had to bleed that on its own first and it sorted the problem. we havnt blead the master cylinder yet no so that might be a good shout cheers Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 27, 2011 Author Share Posted January 27, 2011 Did mine this morning, had to rebuild both rear calipers, one needed a new piston and the other the pins has seized, calipers were easy to overhaul, do think for what you get in the overhaul kit from Toyota its a little overpriced but the piston was cheap. Stuck the calipers back on and bled the system in the order I found on here, no gadgets used just some hose, a spanner and a bottle. I have one of the those "Easibleed"" kits which conects to a spare wheel to pressure bleed it, would be great if cap supplied in the kit fitted the Supra brake fluid tank lol I drained the hole system though of all the old fluid, were as you just had to bleed the two rear calipers, cheers though mate Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 27, 2011 Author Share Posted January 27, 2011 Was the system empty? Did you bleed the master cylinder before trying the calipers?

Scott Posted January 27, 2011 Share Posted January 27, 2011 Yes completely empty and havnt blead the m/c yet but think i will at the weekend, thanks mate That's your problem right there then bud I think the ABS system will bleed through automatically as you bleed the calipers. I could be wrong though, I just know I didn't do anything special. Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 27, 2011 Author Share Posted January 27, 2011 Ok so that means buying more brake fluid, the mrs will be chuffed lol. its been nothing but cost since i bought it Quote Link to comment Share on other sites More sharing options...
ulysees Posted January 29, 2011 Author Share Posted January 29, 2011 The Lithuanian (paint sprayer) guy from work came from Nottingham to me today and with no tools no gimmicks just blead it like a man and boom job done in half an hour, brakes feel like new. A lot of air came out the system. That doesn't say much for the so called mechanic at the garage does it. I am now a happy man again, so i treated her to a wash inside and out. Happy days. Thanks for all your advice and input guys. Ive learnt one thing though.........if you want a mechanical job doin properly(get a painter to do it) lol.

Scott Posted January 29, 2011 Share Posted January 29, 2011 People should be doing their brakes on their own imo, bleeding them anyway. As long as you have common sense and take your time it is a very easy job to do... and you know it has been done right. I don't trust "mechanics" as far as I can throw them. You will find most people are the same hence why they only recommend proper car enthusiast mechanics/engineers to work on their cars. Most mechanics are just brake pad changing spanner monkeys nowadays, IMO of course. Quote Link to comment Share on other sites More sharing options...

kjgreen3 Posted January 29, 2011 Share Posted January 29, 2011 Happy that it was a simple cheap fix like people have mentioned probably just taking your time with it made it easier to get the remaining air out of the system. Quote Link to comment Share on other sites More sharing options...
