Folks, what I'm looking for is an "order of work" to start this. I have an 88 MJ. I run stock size tires, so I'm just replacing stock with stock. All of the DIY's I've found are for upgrading and haven't been a straight-up, basic, replacement vid or write-up. For example: Do I take the old booster and MC off as one unit? Is there prep before I remove anything? Plugging hoses, draining, etc.? There is plenty of info on specific tasks, but I'm not finding the "hand-holding", for lack of a better term, that guides me where to start. I hope this makes sense. Any help is greatly appreciated.

Brother, I live in the mountains. I've my brakes go out before. YES! I do need brakes!

I was at my local Restore recently and I ran across, what I think, are Jeep prototype hood ornaments. One for the Pioneer and one for the Golden Eagle?

Thanks! I decided to go with a reman from NAPA. This will be an adventure!

Okay, so I'm looking online at my options for this repair. I might as well replace the aging booster along with the MC. Now, I'm having to decide which way to go. Reman, new or rebuild kit for MC. I have no experience with this procedure so input is welcomed. I checked the DIY Forum, but only found posts for upgrades and swaps. Not a stock replacement. And @cruiser54 I'm reading that "Raybestos, Wagner, Bendix, Centric, Motorcraft and Delco brake parts are made in China/Taiwan. David Zeckhausen President, Zeckhausen Racing". Who's left?

Actually, I rarely "pound the keyboard". But, right now I need to address the braking issue.

Just some of the ground refreshing. I'm slow to get to it.

Okay, I did it! And now it's as clean as a dirty whistle! Can't be 100% sure, but I think it does run a bit better.

Oh, okay. Hadn't had a master cylinder go out on me. Didn't know the symptoms. Thanks! Any recommended parts brands? I'm not going to scrounge around a just yard for this.

One day my brakes are good, another day (today), the pedal goes almost to the floor! It still stops, but the pedal travel ain't right. 88 with stock system. The booster has been hissing since I got the MJ a couple of years ago. I cannot build pressure when the truck is on or off. Fluid level is good. Maybe the booster bought the farm? If so, is that a pretty straightforward procedure?

Sure. It's running now as long as I don't let her sit for too long. Then I have to do the ol' CPS unplug-n-replug. Ordering a new CPS today. Crusier54 can you verify that the grounds that I addressed at the top of this thread are all that are usually connected to the dipstick stud? I your notes, you mention quite a few components being attached there. I only had two connectors.

Thanks for the replies. Prior to the ground refreshing, I was having an issue with the engine turning over and over and over without starting. I unplugged and replugged the CPS and all was good for the past week. After the refreshing (Friday 6/25) is when things got worse. CPS trick worked again. It sat for three days, tried to start today and no-go. So, I tried the CPS trick again and it worked. Runs good, drives good. Just tried another start and it started after sitting for several hours. However, there is a strong fuel smell, but I don't see any leaks and nothing on the ground. I know I need a new CPS, but there is something else going on. I think.

I started 1-5 of @crusier54 ground refreshing and now the b*tch won't start? WTH? I have no dip stick stud with grounds. Previous owner(s) moved them to the neg batt cable location. I removed and cleaned two round connectors and the neg batt cable and the stud. Put them back. I removed and cleaned the braided cable attached to the firewall, but not the end connected to the engine. I could not budge it. That's as far as I got. Truck turns, catches and immediately dies. This is my DD, so I need help ASAP. Also found some mystery connectors. One of them a Ford?! I guess should have left it alone. No good deed goes unpunished.

Been looking around for a suitable replacement for the part shown. Is the hole diameter on the threaded end important to function? If the hole was larger, would it matter? Also, cruiser54 did you pick this brass connector for a more permanent solution or is a nylon option not available? Would this fit, for example? https://www.amazon.com/Dorman-47057-HELP-PCV-Elbow/dp/B000JZI1U2/ref=pd_rhf_se_p_img_1?_encoding=UTF8&psc=1&refRID=01Q7SDFB930V62TGYWTC

cruiser54 Is there an option to the NAPA vacuum fitting? It's not in stock at my local store. They want to charge me $22 in shipping and I have to order 5! I'm not playing that game.

Okay gents, oh wait, that be insensitive. Okay non-gender specific Jeep Comanche owners, @Strokermjcomanche The MAP sensor plug on the throttle was completely unplugged. Put that back. However, I have noticed that mine has a hose connected at bottom, whereas I have seen many with that same hose connected at top. Does that matter? @87MJTIM I do not have Nickintimedesign's REM. After reading about it, sounds like a must-have. @cruiser54 I hate always saying that I have not does the grounding checks. I'm concerned that it will take so long that I won't be done when I need to go somewhere. I know that's lame. Could the stalling be because the Map sensor/Vacuum system had to re-pressurize before it started running smoothly? It's running pretty well now. Also, this morning, I did the CPS-uplug-replug trick due to no start. It's done this of-and-on recently. Turn over several times with no start, but eventually does start. The CPS trick worked, so I guess I need to replace something there. While digging around for the CPS, I decided to take a pic of two unconnected sensors. ID on those?

My 88 was running poorly recently so I replaced the Air Filter, Fuel Filter, Plugs (they were black!) and Wires and Dist cap. The link is really just for audio so you can ignore the video part. It started great, ran for about 90 sec and shut down. Started it again and it started doing what's in the video. Shortly after I stopped recording, everything seemed to straighten out. Is this normal after new parts?

I'd like to consider ratting my MJ, but all these straight line don't seem to allow for much visual interest. Seems like all guy's do is lower it. No interest in that.

My 88's been my DD for the past 3 years.

A disassembled piano. Heavy, heavy, HEAVY!

This a is textbook example of "seemed like a good idea the time" huh? They get hot for sure. Mine stopped steaming after I replaced the cap on the overflow bottle. And, I don't lean on the hood after a long drive.

Boy ol' boy! That's a can of worms! I love mine and earned them through a work trade. So, no cash, just did some work for guy. Some folks get them for free too. And some folks trade for parts. The tire looks good, so that's a plus.

UH OH! Serious dash modification on the horizon!

Sweet! I have an oldschool Rockford Fosgate Punch 45 amp, but I'm intimidated by the wiring. Guess I'm not man enough for it!
