Brake bleeding

Discussion in 'Mech Tech' started by AndyC, Apr 30, 2018.

  1. I tried to bleed my brakes with a Gunson Eezibleed, but the brake reservoir screw top would not hold the pressure. Kept leaking and a fine mist spray comes out!

    Can anyone recommend one of the kits when you have a one way valve on the brake nipple, and you just keep pumping the pedal to bleed it?

    Open all 4 bleed nipples, wait a minute, look for air coming out of the nipples, tighten up, job done

  3. If the mist has brake fluid in it, it's the best paint stripper in the business!

    No mist, just drops, no pedal pressing

  7. Had a problem bleeding my MG and then my brother suggested 'Gravity bleeding' Very simple and worked for me. The m/c is above the brake nipples so will work by trying this method. Back first, place a brake bleed tube over nipple, open end in a jar, open bleed nipple until fluid flows out. Do not press pedal, just watch the fluid and air bubbles slowly flow out, top up m/c and tighten up bleed nipple when all air has escaped. Then the other side and then the front brakes. 40 mins job done. Give it a try and good luck. nb do not need the one way valve

  8. Tingled a bit as it went in my eyes!
     
  9. Just let gravity do its thing?
     
  10. The leak was probably caused by too much pressure; you only need a few psi to push the fluid through the master cylinder. I’ve used an Eezibleed for years and I have an old spare tyre with about 5psi in it, that’s plenty.

  11. I think I had it quite low. Maybe go lower next time.

    Yup
     
  16. If there is 2 of you just do it the basic simple way, done in 5 mins put some pressure on the pedal and really knock out the grotty old fluid .
    Providing your nipples are free and easy ....Oh a say what was a thinking .

    My easy bleed kit works perfectly, have you got the right washers on and not too much pressure in the tyre you're attaching it to, 20 psi max,

  18. I bow to @davidoft ‘as knowledge as being much better than mine.
    But if you can’t get that to work then the simple way using a bleed pipe with a non return valve works for me every time for about £5
    Really interested in trying &Davidoft ‘s solution next time though!
