I measured the depth of the cup from the booster and noted about 3/8 difference between the original and FJ80 MCs. Made me feel better. I ground 3/8 off the booster rod (thanks for the warning on keeping the shaft pristine). Worked great. I now have brakes when I want them - not...

Thanks for the replies. I had also read that this was a bolt-on conversion with relatively little hassle - thus my reluctance to remove metal. At this point however, seems that's the problem. I'll do some judicious grinding and let you know how it goes. Honestly, I'm glad to see how well the...

Manny, I tried your maneuver. After pulling the MC off (following advancing the booster rod by 1/4") - there is no play (unable to push rod any toward the firewall). So my booster rod is too long. Before I start cutting and grinding, I need to make sure that's the right move, though suspect...

Steve, I tried this after a warmup (got the brakes warm and increased the drag). Backing the MC off 1/4 inch definitely decreased the drag. Tried tightening up again - increased drag. Tried this with the rig running to engage the booster - same results. See reply to Manny (tried this...

Steve, Thanks for the advice. I greatly appreciate the response. Will do the above today and try to get some photos up. Will also try Manny's advice and let you know. Mark

Manny, Thanks for the advice. I adjusted the booster rod all the way down prior to getting this response (screwed the acorn nut down so no threads showing). Still no play. I will try the technique described above; though, I'm not sure where I'll get any extra play since I've adjusted the...

I recently installed an FJ80 MC in my 71 FJ40 (4 wheel discs) when the stock MC failed. After some challenges with bench bleeding the MC I thought I had it nailed. After an initial test drive, noted lots of drag. There is virtually no pedal play. I raised the front and rear up and noted...

Having just spent several days playing with my MC and brakes, I think this is the master. The only way for fluid to "reflux" into the reservoir is to have an internal seal leak so that some of the fluid you're trying to push through the brake lines is coming past the seal and into the...

Mendocino and ohrly? Thanks for the advice. I'm wearing my sign. Bench bleeding did the trick. I now have outstanding stopping ability - made a HUGE difference switching to the 80 MC.

Thanks for the advice (I can't believe there is a video of bench bleeding...). Will do and report progress.

I did search the posts on bench bleeding. I essentially did that by loosening the compressions fittings and pushing out the air/ brake fluid in the front. But again, no fluid to the rears. Any ideas?

Here's where the rampant ignorance part comes in. No I didn't. Walk me through it if you could.

First of all, I confess to rampant ignorance and malignant stupidity. That said, I need help. I replace the old tired master cylinder in my 71 FJ40 with a new Aisin FJ80 master. It bolted up nicely. I thought I might have a relatively easy project but... The master is pumping fluid to the...

Thanks for the advice. I did recall that rounding off was a bad thing so I've gone slow. Having read the postings on the challenges of flaring, I'm a bit anxious to cut the line. This may turn into a multi-day affair. I am using the PB blaster and appreciate the referrence to the line...

I recently replaced all 4 brakes with discs. Had problems for a while with "double pumping" the pedal to get the truck to stop. Well that resolved itself to the point now that double pumping no longer helps and stopping power is diminished. Tried bleeding again to no avail. I've noted the...
