cainhead Posted December 11, 2013 Share Posted December 11, 2013 Can somebody clarify a few bits, better yet just point me in the direction of a how to bleed brakes step by step instructions. I have abs, which seems to be the bit I don't get. The pedal hits the floor and barely stops the car. I hope it's just air in the lines but if it's master cylinder etc then so be it but I still need to check simple things first. At least get them working enough to get it to my garage. All help greatly appreciated Quote Link to comment Share on other sites More sharing options...

cainhead Posted December 11, 2013 Author Share Posted December 11, 2013 If you can get your hands on one a vacuum bleeder makes the job very easy and you can do it on your own I saw your previous posts on this. Had a look on ebay for one. Will put the misses to good use for now and save myself the cash. But worth the investment in the future.

cainhead Posted December 11, 2013 Author Share Posted December 11, 2013 One question. Reading through the manual it said to pump the fluid through until non comes out the tighten the billed nipple. Would I then need to fill the resovoir with new fluid and pump that through for each wheel. Quote Link to comment Share on other sites More sharing options...
Dnk Posted December 11, 2013 Share Posted December 11, 2013 You need to keep the reservoir topped up or you will draw air into the system and get nowhere Quote Link to comment Share on other sites More sharing options...

Nic Posted December 11, 2013 Share Posted December 11, 2013 (edited) Turn on engine so it's ticking over. Start at the wheel furthest from the brake fluid bottle. Unscrew bleed nipple quarter of a turn. Press a length of clear hose over the bleed nipple and the other end into a spare bottle to catch the fluid. Top up brake fluid header bottle. Get the wife to pump the brake pedal a few times. You'll need to keep checking and topping up the brake fluid bottle, if it runs dry you'll suck air into the brake lines. Keep pumping pedal until the fluid runs through the tube without any air bubbles. When the fluid in the tube is running clear with no bubbles, get the wife to hold down the pedal, as she does tighten the bleed nipple, just nip it up, careful not to over tighten it. Repeat above, working on next furthest wheel from the brake fluid bottle. Last caliper to be bled will be the one closest the header bottle. After you've bled each caliper, check you have a firm brake pedal, if there is too much travel or it feels soft there will be air in the lines somewhere and you'll need to rebleed each caliper again. Once done, double check there is no brake fluid leaking from any of the bleed nipples, calipers or brake lines, then top up the brake fluid bottle to max line.

cainhead Posted December 11, 2013 Author Share Posted December 11, 2013 Cheers Nic, that's the simple answer I was after. I'm one of those people who can do the complicated tasks but struggle with the straightforward ones. This will be the closest the misses gets to driving the supra Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 11, 2013 Share Posted December 11, 2013 Or just get the not-expensive vacuum bleeder and do each corner in a couple of minutes, and infinitely better than you'll ever achieve with the brake pedal method Quote Link to comment Share on other sites More sharing options...
st3ven1 Posted December 11, 2013 Share Posted December 11, 2013 If you're not getting a firm brake pedal after that then it'll be worth thoroughly cleaning the back of the calipers especially around the bleed nipple as the caliper can crack. Might not be obvious at first but if you get someone to press the brake pedal whilst you check around the bleed nipple, it'll show up any cracks. This isn't uncommon on the J-spec brakes.

Dnk Posted December 11, 2013 Share Posted December 11, 2013 Use brake cleaner and hard toothbrush to clean the calipers, halfords sell it Quote Link to comment Share on other sites More sharing options...

I bought one but I found it absolutely awful to use. I couldn't get a decent vacuum seal around the bleed nipple. I've read the recommendations about using vaseline to form a good seal, but loosening and tightening the nipple broke the seal every time. It's probably rubbish technique on my part.

Ian C Posted December 12, 2013 Share Posted December 12, 2013 This: http://www.ebay.co.uk/itm/Sealey-VS402-Vacuum-Tester-Brake-Bleeding-Kit-Cars-Bikes-Automotive-Garage-/121087068169 Bargain. I too had the same problem you mention but I used automotive grease and a lot of it. Smear it around the nipple's threads and caliper as well as where the vacuum tube end goes on the nipple and you get a perfect seal. Be generous Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted December 12, 2013 Share Posted December 12, 2013 If you struggle to get the vacuum hose to seal, use a 3" piece of 6mm silicone hose to fit between the bleed nipple and pvc hose supplied. The silicone seals much better, and doesn't require grease and messing about Quote Link to comment Share on other sites More sharing options...
Dnk Posted December 12, 2013 Share Posted December 12, 2013 (edited) We used a Mityvac bleeder like this one, didn't have any issues or mess around with grease as far as i can re call, just crack open the nipple and bingo, keeping the mcr topped up along the way. It too longer to walk round the car than bleeding all 4 calipers Brakes were 100% spot on afterwards but we had fitted brand new UK spec calipers all round with new braided lines and Motul RBF600/660 fluid Edited December 12, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
