Hey all, my brake booster is leaking in the back (filled with fluid) and it's leaking from the master cylinder. I was looking for a new booster and master cylinder, I'm finding there is a 1inch and 3/4" sizes? What one should I get? This is a 91 W250 with a 4500 front end (dana 60).

just my luck

 

Neither, it's 1 1/8".

 

Anyone have a link or partnumber? The check valve is 3/4" and 1" is what I was talking about. It looks like what I have, I was planning to get rear disc brakes at some point so I don't know if I should go with a universal setup or stick with the stock.

 

I think I have a 3/4" check valve, will have to look tonight.


This looks like a good deal, although I never heard of cardone before

Good brand?

 

Cardone is garbage. Hate all their products, Used them all with horrbile results. LOL.

I usually buy Bendix or good name brand stuff off rockauto.com and just wait for it to get here.

 

Yeah, I might go with the centric brand, they make good stuff and are a branch from stoptech.

 

I wouldnt cheap out on parts! I installed two rebuilt masters, and got two bad ones in a row. Finally put in a new one and the brakes are as good as they've ever been.

 

Bumping this back up, I'm having a hard time finding a brake booster. They're all A1-cardone crap.. I did find a few centric boosters but they have many different numbers. The only difference I can tell is the check valve is bigger. What does the check valve do? Would a 1inch give better performance to a 3/4"?

 

i am pretty sure A1Cardone is the only one re-manufacturing the boosters and A-lock valves. I cannot find anyone else...Mark

 

If you scroll down here; There are a bunch of centric's

I've been using Centric rotors/pads for awhile and they're really nice! Although I don't know what one to get.

 

Cool, I don't think the size of the check valve really matters. I have had bad luck with A1Cardone so I will try one of these next time. Do they make mated units?...Mark

 

Just got off the phone with them. This is how it works.. you pull the brake booster out and on that push rod there is a code on it. Keep in mind that if the brake booster is not stock this might not work

Rod Code(s)

13849
14177

Centric Part# - 160.80.244

Rod Code(s)
13851
14180

Centric Part# -160.80.245


Rode Code 1"
14180

Centric Part# -160.80.250

If the rod code matches the above, then the booster you need is the part number below. Awesome! Looks like I have some work to do haha

Also this was for a 91 W250 but apparently those codes are what was used on the assembly line. They will work with a D250 as well as long as it's 1st gen series. If the code is different, give them a call (626.961.5775)

 

is the centric MC...looks new...Mark

 

Sweet! I should be ready to rock once I find out what booster I have. I'll let you all know how it brakes!

 

Cool. I'll be right behind you...Mark
