Just like some folks say, "become your own warranty station", it's become your own self adjuster.
I've spent countless hours tring to get them to work, can't see why they won't when everything is apart, but they just don't work.

 

How 'bout the old put her in reverse and stomp the pedal gig. Does that work on our trucks? All I know is that those two inexpensive cylinders and a little instal timemade a huge difference on my 98 2500 4X4.

 

Is the master cylinder on a 1997 dually the same size as a 1997 SRW?? if we upgrade to a 30mm cylinder wont we have a problem with tire lockup and the master cylinder needing to be bigger???

 

All post '97 CTDs have the same 27mm cylinders.
Sure, you can lock up your rears until you learn to use the new braking power. Master cylinder has plenty of capacity for the 30mm cylinders.

 

I have rear ABS which helps not locking up. Not that ABS is perfect but it helps

 

Here's the quick math:

Switching from a 27mm to a 30mm cylinder increases applied force area from 572.55mm^2 to 706.85mm^2.

That's over a 23% increase!

This should be a good mod, but I can't use it because I have an '02 and already have great braking

On saturday I replaced the stock rear load sensor rod with a device made from the balljoints of a Merc. Benz 207 throttle linkage and a threaded rod about 15mm longer than the stock rod on a friends 97. Costs nothing (parts were from a wreck), and it's adjustable. Very good braking now (with the stock cylinders) and about 10 minutes of work.

Something to be considered for anybody who still has good rear cylinders or lifts his truck or the like.

I will do mine asap this sounds great my brakes suck..

 

Did my brakes tonight it took all of 30 min to get it done, I am not happy at all,have not seen any diff in them at all very disapointed even adjusted them way up I even bought the wagner brand and took the rubber boot off to make sure they were 30mm and yup the are but dont work...TJ

 

Dieselman24- try to disconnect the rear axle load sensor (proportioning valve) rod to the axle and tie it up to the frame with a ziptie or the like- sometimes the proportoning valve assumes that your rear axle is veeeery light and won't let enough pressure get to the cylinders. (It could be that the proportioning valve is bad too)- Try it on a road that's not frequented, vehicle could sway or fishtail when applying brakes!

Just bought a pair from napa, infidel's part number. 10.29 each plus tax...hehe i love it cheap fix!!

 

Ebottema, you have a 96 2500 right? Let me know what you think of this mod, I'm highly considering it on my 97.

 

You got them for $10.29????? When I bought mine they were $12.99 each. They do make a DIFFERANCE!!!!

 

I will have to try this and gee I hope it fixes it..Cause Im very disapointed in them....TJ

 

I installed the Dodge 1 ton cylinders on the rear and see no difference. I have a 96 4x4. Are the GM cylinders better?
