Author Topic: Bleeding brakes... (Read 13635 times)

As in the title, I've fitted new brake pipes and filled the resovouir with fluid but pumping the lever does nothing to move the fluid if that makes sense. Question is any suggestions or tips. I've left a bleed screw open and fluid in the resovouir hoping it will bleed itself.

perhaps try open bleed screw,pull lever=hold,tighten bleed screw,loose go of lever,,,,,,,repeat

like the old dances you go to

I have found in the past having the bleed nipples closed helped to get it started. as soon as you get fluid in the line it is easy. Don't be tempted to open both nipples at the same time, do one 1st then the other and go back etc.

if that fails a brake bleed/vacuum tester is a great tool to have.

in truth this is how I generally bleed brakes now days. saves hassle and less chance to get air in the lines.
Good luck

Yes tried that and also tried a non return valve type bleeding gadget. Once I've dropped off the wife's car for a service I'll have another go tomorrow.
Cheers

I have read that people use an oil can to do what is being done in this clip.

I think you would need to use a new oil can.

Be careful doing this mate - but put a long tube on the nipple, open it, and suck. Eventaully fluid will come through. Make sure yuo're filling the reservoir up. Use a long hose though so you don't get a mouthful! Then do the same for the other side. Once you've got pressure, you can bleed as normal!

Failing fJoe's method, you can always try the reversebleeding which may work better with the cylinder seals. Worked on m y Fazer.

Try Use the old fashioned oil pump can like the attached pic to pushh the fluid back up to the reservoir. Make sure the oil can is full of fresh fluid and the reservoir cap is off.

I'm pissed and this haw taking me ages to type. Good liuck fella

Also make sure pistons are pushed right back in calipers.

close nipples and leave the reservoir cap loose overnight with the brake lever bungee strapped to bars.
In the morning it should bleed fine.

Andy FZS · « **Reply #12 on:** 11 February 2015, 06:05:35 pm »

Bled ok today, lever feels ok. I'll give it a week or so and bleed them again just to be sure I've got it all.
Cheers for your suggestions.

Sorry geezer, I am really getting a case of "can't be arsed".... but hey, clearly don't know what you doing, why not do you're own brakes with help from internet experts" its not as if they are vital is it? ..... Crack on.

Andy FZS · « **Reply #14 on:** 11 February 2015, 07:24:57 pm »

Don't assume that because people ask questions it is an indication of their ability . If you don't wish to help others with your vast experience that's fine.

I don't mind helping people out but I'm not prepared to help someone kill themselves or others. Its very clear in this case Andy FSZ you're out of your depth here matey. It's like with most things if you know what your doing it's easy and there are countless books or people who are prepared to offer "the best way to do it" because it's easy

There is quite a few pit falls with bleeding brakes to the point where they appear to work until you grab a handful in an emergency and they don't work

. Mate seriously get someone who knows what there doing sort them for you, don't listen to some of the advice given below it's just plain comedy

Deefer666 · « **Reply #16 on:** 11 February 2015, 09:11:05 pm »

Thanks Gnasher..... The voice of reason that I should have been but sometimes you just have to read this stuff and it's best to shake your head and walk away.

Andy FZS · « **Reply #17 on:** 11 February 2015, 10:11:26 pm »

Thanks for all your concern but fortunately you don't me or my ability experience and qualifications you've made assumptions that are wide of the mark. I'm sure your comments are well meaning but in this instance wrong. Anyway thanks for your concern.

And, no doubt, you were *born* knowing "what you're doing", so it was easy for you.

For those of us who aren't natural born geniuses, we have to ask questions and it's nice when we get helpful answers rather than "you're out of your depth, get someone else to do it!"

Deefer666 · « **Reply #19 on:** 12 February 2015, 08:18:26 am »

My despair was more aimed at answers being given.... Like I said "Can't be arsed" anymore

BBROWN1664 · « **Reply #20 on:** 12 February 2015, 08:56:32 am »

Gnasher/Deefer

I am more than capable of bleeding brakes and taking on most tasks mechanical or electrical having had a 4 year apprenticeship in doing these things but even I had to go and ask for help when I fitted braided hoses to a bike a few years back because no matter what I did they didn't want to bleed using all the normal processes I had learnt over the years.

I do agree thought that some people shouldn't give advise

maddog04 · « **Reply #21 on:** 12 February 2015, 10:02:22 am »

I'm glad deefer still pops in, how's old ma and your lad getting on?
how's the business doing and do you still hear off nooj or matty?

Deefer666 · « **Reply #22 on:** 12 February 2015, 10:29:00 am »

OMF is fine, we are just so busy with Fat Maggot Clothing & Motorcycle Republic at the moment, you know what they say when you work for yourself you have to work twice as hard. Our Lad Matt is now 21 and works in a gym, complete bodybuilding, fitness freak and built like a brick outhouse. Motorcycle republic has really declined recently and I am starting to question its validity, I am at the moment disposing of all the amassed fazer stuff that I have acquired over the years... So many sets of crank cases, maybe theres a market in turning them into coffee tables or something.

I still speak to Nooj and see him occassionally, He is doing well with his Shiny Bike Syndrome business, I haven't seen Matty in years.

maddog04 · « **Reply #23 on:** 12 February 2015, 10:32:15 am »

shame about mc republic but great news on fat maggot, OMF and your lad. Glad he's doing well now after the scare a few years back. I bet he's still not big enough to take you tho!!
nice to hear nooj is doing ok, shame about matty
