front brakes

[macgillivary]

I just picked up a banshee in pieces

Anyways doing the front brakes, I put new pads on

 

When i was bleeding them everything was fine

 

But now when you pull the lever first there is very little grab, like you can pull it into the handlebars and the tires wont lock up but if you keep pulling it it grabs better and better, if you pump it like 3 times they lock up no problem

 

I bled these sluts about 40 times and its still the same

But Ive been bleeding one side, then pump them more and bleed the other

Also noticed a small fluid leak near the rezzy on your bars but cant figure where its coming from, the bolts are tight on all the lines

 

Any suggestions why they wont stay strong? Bleed them at the same time? Bleed them more? or is it something to do with the small leak

Thanks

do you have the little copper washers for your banjo bolts?

do you have the little copper washers for your banjo bolts?

i thought about that too. and if you see fluid leaking somewhere, there's a chance you may be sucking air in there also. :shrug: but you should see air coming out if you've bled it over and over. what about the set screw located near the pivot point of your lever that pushes the piston on the res, how is it adjusted? maybe you have a bad caliper. :shrug:

If you are not leaking any fluid then you most certainly still have air in the system. I have never had any of my Banshee's front brakes bleed very quickly. You have to bleed them, then bleed them some more while you are tapping on the calipers, lines, and master cylinder, then when you are done doing that bleed the system some more. Aftermarket braided lines pretty much make the bleeding even worse for some reason. Have fun. :thumbsup:

Here is a really neat trick. Take the banshee front master off and throw it in the garbage. Then buy yourself and front master off a yfz 450 and install that one. For some reason, the banshee masters dont like being bled. Even if you rebuild it. I had the same problem, i tried everything, had 3 banshee masters. Nothing. So i got a yfz 450 master for 20 bucks on ebay. Didnt even bleed it, just put it on, filled with fluid, and hard a a rock brakes.

Have somebody pumping the lever and look closely at the rubber hoses at the caliper, if they are old they can expend and thats why you are losing pressure on the first aplication of the break. Ive seen it many times on cars and trucks.

I bled those fronts for a long time & had the same problem even though I kept bleeding. I finally got a bleeder $10 & I can see all the air bubble escaping thru the clear tube. A friend bought a vacum pump $40 and finished his lines quickly.

I bought the mityvac and you can pump them in about 5 minutes.
