Hey guys I have a problem with the brakes on my Scrambler 400 that I bought a few months ago. When you pull the handle for the front, there isn't any pressure at all. I replaced the actual master cylinder but not the handle and everything. when I open up the valves and pull the handle the brakes will bleed, but it doesn't help any. Any suggestions?? Thanks

 

hi,leave the cover off+gravity bleed while keeping it filled untill you lose an ounce, close bleeder,put cover on, see if you have something.

 

sounds like u still got air in the lines, keep bleeding the
brakes again & again, u should slowly start to feel the
lever firm up. Make sure u keep the brake fluid topped
off while bleeding or u will keep putting more air back
in the lines!!!! it can take some time to get all the air
out, make sure u hold the lever all the way down when
u open the bleeders up & keep it down until u close them
back up each time u bleed, should have two people to do
this.( u may already know this)

 

yeah that is basically what i did for about an hour straight and had no results.. is there any pressure on the reservoir for the fluid or does that not matter?

 

if you don't see anything leaking anywhere+seems like your bleeding properly you might have a bum master(bypassing internally) i got two in a row for a car.

 

you might be uncovering the supply port, make sure you have the diaphram in,you can try taking off the brake line,leave the fluid in,put covers over things,put your finger over outlet,slowly pump a few times you should feel some pressure,this is bench bleeding.air might be trapped in master,stop,put line on bleed again,wear goggles.-------

 

im curious to see if it has any pressure on the master... i didn't think about taking that line off. thanks

 

on auto's if you don't bench bleed the master it wont build up enough pressure to get rid of the air trapped inside it.

 

HI, CURIOUS IF YOU FIXED.

 

didn't get to work on it this weekend [img]i/expressions/face-icon-small-sad.gif[/img] maybe next weekend...
