Hmmm. I just rebuilt it with a new piston. I wonder if I have the o-ring seal on backwards. I found a cheap hand pump at harbor freight I'm going to try. I'll let you know. Thank you for your help.

...and you can talk to me like I’m an amateur, because I am. No offense here.

I’ve done that. So, when I have the lid off the master cylinder, thumb over the hole and squeeze, I get blowback thru fluid thru the seal at the bottom of reservoir. Should I have that?

If I disconnect the hose from the master cylinder and pump the handle, should I have flow out of the opening?

Hi everyone. Brian McNew here. I’m a Shreveporter. I have an old 1991 Honda I am partially rebuilding. I’ve had it stored for many years. I have cleaned up the back end and am now trying to bleed the front brakes. I now know why this process is reserved for the 7th level or hell. I am having no luck. This is a nightmare and the last thing I need to do. I have watched videos and done everything I am supposed to and cannot get anywhere. I posted in the main forum and here as well. i want to get it back running to go joy riding. Any advice.

I’m rebuilding a 1991 trx300 fw. The brake master cylinder was dry/empty. Hoses appear to be clear. Bleed valves are clear. I replaced the master cylinder. I cannot get the fluid to flow out of master cylinder when pumping handle. I am doing everything per the videos I have watched on YouTube. I can get a few bubbles out of the hose at the end of the bleed valves but the fluid level in the reservoir never goes down. I put my thumb over the outflow with the hose off, squeeze handle, and get some back pressure thru the oil seal in the cup and can feel some pressure and suction on my thumb I'm at my wits end and see why brake bleeeding is reserved for the seven levels of hell. Any suggestions?

Thanks for the info. I downloaded this and it was exactly what I was needing. Got everything just about disassembled. found out that the fenders i bought a few years back are not the correct ones. will need to start a search for the correct ones.

I was given a 1991 Honda Fourtrax TRX300 that is in fairly good shape for its age and what it was used for. I got this to rebuild as a hobby project. What is the best service/shop manual that has parts lists and exploded diagrams so when I go to disassemble I can order the correct parts and get it back together correctly again. Thanks for the help.
