85 250r rear brake trouble need help.

[Dewey3469]

Ok can't get rear brake to get compression. Bought and installed new rear brake master cylinder kit, put a new brake line on as well. Have checked all the lines everything is clear but just won't bleed. It does have extended brake line about 32". Is there any easy way to bleed it. Thanks for help

i seem to struggle every time i put a new line on the back of an R. idk why?? it seems to take forever to get the thing to bleed. there may be an easy way that some ppl on here know.

anyone??

I pumped the rear brake for at least an hour

this works for me:
break the banjo nut loose at the caliper, then push down and hold the pedal, then tighten banjo nut back up, then release the pedal.
do this until you get fluid(no air) at the bolt, then it will give you a head start on bleeding the caliper. takes about 30 min.

Ok so another 1 and half more hours. This time started top bango and had hard pressure worked way down to next bango and had good pressure. Put onto caliper and got fluid to come out but no real pressure. So changed out rear caliper and its the same. Never had this kind of trouble.

I used a vaccum bleeder and "sucked" the air from the bleeder. This is what worked for me. i was having the same problems after I rebuilt the master and replaced the lines on my 200X.

i always use a vacuum gun,, you can't get all the air out very easy without one,, also you can hook a clear piece of vinyl tubing put it on the bleeder screw.. open it up fill the res and leave it overnight... all the air will escape

I have tried many methods to bleed and bleeding at the banjo seems to be the best way. Once I get line pressure then I bleed the caliper at the bleed fitting. Sometimes they can be very stubborn to the point of wanting to light the whole damn thing on fire.

Its trick to bleed the master cylinder for some reason. I drilled a hole in the lid or a old cover I had and lighty blow some compressed air in there and that worked good for me but the correct way would be to get a $7 vacuum bleeder kit from a auto parts store.

Ok so went out bought a 34.00 bleeder and it didn't work but I did what Mr. Kasey said with vinyl tube and fill res it finally bled wow and was ready to burn it. Thanks yall
