Post subject:  problems with bleeding cutting brakes
:x Trying to get everything lined out preparing for trip to LBL this weekend and I fix one thing and 10 more things screw up it seems!!! Noticed my drivers side caliper was barely dripping whenever you pushed brake pedal/pulled cutting brake and ended up having to replace little brass fittings going into caliper, no big deal...Well after putting it back together I go to pump em up and bleed em and the cutting brake won't build any pressure. brake pedal has all kinds and works fine, I've bled and bled the drivers side hand brake and although it's getting fluid, still won't pump up to where its always been. But, if I hold the brake pedal down, I can pull the hand brake and it feels great, just as it always did. I've came to conclusin that I've just got air in the system but I've "burped" all the lines that I have and haven't had any luck. Cutting brakes are twin handle Neals' and do not have bleeder on them. Any suggestions???

I had a frozen caliper once that gave me a great foot pedal but the cut brake would not bleed for nothing. It did not make sense but that was the cause.

iv used to always have trouble with cutters until i realized they need to be bench bled just like the master cylinder does.

unbolt your rear calipers and put a block of wood between your pads and raise your caliper as high as you can and then hold your brake pedal down open bleeder and pull your cutter....works everytime

Post subject:  Re: problems with bleeding cutting brakes
tried this last night and still not having any luck... I'm getting plenty of fluid but the cutter just won't build any pressure unless you hold brake pedal, then it feels normal. It's got air in it I'm almost positive, just matter of finding out where and how to get it out

If you tried the above then try this. There has to be a check valve (a BB in a tube )(pressure 1 way only) or a shuttle valve(a BB that shuttles one side to the other inside the cut brake).When these BB's travel in corroded tubes and one day for some reason they get to travel a distance they never traveled before into some cruddier passages they get stuck.Now. it's back to what I say. I hate everything California screws us with. Build your ride from factory Pull a Part stuff. :?

Post subject:  Re: problems with bleeding cutting brakes
Good point :D . If you look at the Panzerwagen or the Passat, the ONLY thing you will see from California are cutbrakes. And they, like foot brakes are designed to bring you back in a year or 2.The cutbrakes in the panzerwagen are acting up now. Those IMI starters aswell. Why do my grease ball junk yard starters last forever.I don't have time to go on and on...

Try tilting the cutter brake assembly forward and to each side while bleeding to allow any trapped air to get out.

Make sure your cutter brake piston's are returning all the way so the the fluid transfer ports are not being covered up. There also needs to be some end play in the Handle(s). You can only remove the air if fluid is replacing it.

I forgot to add what brake system I'm using my bad... Only thing I'm not sure about is the master cyl, looks to be stock (has the "clip on" top ), using nissan sentra calipers & Neal turning brake assembly

you got me interested. i got dual handle neal cutters. they are soft and don't grab til about 5k rpm. course i can't bled like they were sayin either. if i hold the pedal down the pressure holds my cutters in place. can't use brake and cutters at same time.

Brakes shouldn't be a function of the motor RPM's :?: To me it should work less.

its as though they cant slow the wheel enough to make a difference unless its tached out

Push the footbrake down to build pressure, then pull the cutter and have your assistant open the bleed valve, might shift it.
Never release the cutter handle after that, once they shut the valve keep the pressure on the cutting brake and pump it back up with the pedal.

Post subject:  Re: problems with bleeding cutting brakes
I've done everything that everyone's mentioned on here so far with my buggy as well and none of these trick's have worked.When I Bleed my brakes, this is how I do it. I push the footbrake down to build pressure, then pull the cutter and have my assistant open the bleeder valve, I never release the cutter handle after that, once they shut the valve keep the pressure on the cutting brake and pump it back up with the pedal.......I've done this with both side's. I've taken all the calipers loose and mounted them to be the highest points, so that hopefully the air would travel up. No luck! I've picked the ass end of my buggy up with our new holland till it was hanging straight down simulating I was coming off a cliff and tried bleeding the rear caliber's that way. Still no luck..... If I hold the foot pedal down the pressure holds my cutters in place and they're hard. Soon as I let go of the foot brake though, my cutter's go back to a sponge. When I climb hill's, I actually have to feather my foot brake, in order to use my cutting brake's which kills my momentum. I even bought a hand vacuum brake bleed pump from autozone and this didn't fix it. I'm considering going to a floating set of caliber's.

After bleeding and setting for awhile, do keep getting air when you try to rebleed from one of the calibers?

No, after sitting up, there's nothing but a constant stream. no air.

Then you might have the right idea about a floating caliber.
