I am bleeding my brakes. No more air coming out of the bleed tube. Brakes have very little to no prssure. Each side moves a little but really no pressure. I do not have the drums on. Is that the reason.

Thanks

It could be. The drums need to be on before you bleed the brakes. The plungers in the wheel cylinders are probably coming out too far and letting air back in the system faster than you can bleed it out. Put the drums on and bleed them and see how it does.

I am very new to this. Do I need a bleeder kit for this job or can I get away without one

I always just bleed them by pumping up the brake lever and holding it down while loosening the bleeder screw. Tighten the bleeder screw back up before releasing the lever. Bleed each wheel until all the air is out. Make sure the brake drums are on before bleeding. Make sure you don't let the reservoir get even close to being empty or air will get back in the system. Also, before starting to bleed, make sure the brake shoes are adjusted up.

All great points. THANKS

Agree^^^^^ another easy way is to remove the resi cap and loosen the bleeders stick a screwdriver in the little plunger hole in the bottom of the resivior and let it sit there for about 10 min. dripping fluid just make sure you keep it full. close off the bleeders and refill resivior to spec level.

I use that method sometimes, if I have trouble bleeding them by pumping the lever.

I had to buy a mightyvac pump at the autozone set up the pump hook the hose to the bleeder pump the vacumn crack the bleeder and suck the fluid through the system works really good and fast. just be sure to keep the res ful of fluid cause it will suck it through fast.

Strange. I pump it up, open the bleeder and fluid comes right out...no air.. But I can easily pull the brakes all the way. They do catch but not hard. I thought it could be the master cylinder but if it was that I would not be able to build up pressure...

If I pump the brakes should they get harder and harder (like a cars)? After a few pumps should I not be able to pull them?

Yeah, it should pump up and get harder to pump. Try pumping the handle real fast. Make sure you have the brakes adjusted up good or you won't be able to bleed them good.

If you can't get it to bleed using this method, try gravity bleeding like Moose suggested above. Fill the reservoir, stick a screwdriver in the rubber piece in the bottom and loosen the bleeders, but make sure you don't let the reservoir go dry or even low. Stand by it and keep topping the reservoir off with brake fluid. When fluid is running out the bleeders steady, with no air coming out, tighten the bleeder screws and top off the reservoir.

It might be easier to have someone help you while gravity bleeding, so you don't let the reservoir go dry.

I have been trying to get pressure to build in my front brakes for weeks. I have bought a new res, tried bleeding in multiple variations (not tried gravity bleeding) and can't get good pressure. I have an 87 Honda TRX350 4x4. When I pump 12-15 times really fast, it builds pressure. When i loosen the front left bleed valve it shoots fluid 6 inches but when i build pressure and loosen the front left, it only trickles out a tiny bit. Do I have a clog in my system on the front left? I pumped it with the shoes off and the plungers rose on both sides as I built pressure. I am thoroughly confused!!! Good thing my back brakes work (as good as back brakes on these things work

I had a similar problem recently on a 88 300 , the right side was get no fluid to the wheel cylinder , it was a rust clog inside the fitting at the end of the hose , it was clogged up that it took a drill and bit , the 88 didn't have banjo fittings on the brake hoses like the later models do , I would think your 87 350 would have the same style fittings , a straight fitting with a swivel connectors to join the hose and wheel cylinder , try pushing a drill bit by hand thru the fitting

i got an 88 300 and we bleed the breaks and i still dont have near enouff presure but the pisstons mobe

Try clamping the rubber brake hose right at the mater cylinder with a pair of hose pinch pliers , if you don't have those pliers , use a small pair of vise grips with some rubber of card board around the hose so as to not damage the hose , if the master cylinder is good then the lever should get hard quick , if it doesn;t then the master cylinder is bad
