Re: Rear brake upgrade: 11” to 13”
 

LMAO. Ass transplant! I gotta register there. Nice 14B. I gotta ask, where in the hell does the Oreo come into play? Does it help calibrate the dial indicator :haha:

I didn't read it all of the way through. Do you like the ARB? Ive got a Gov Loc. It hasn't given me any problems but if it were to go, I was looking at either ARB or an OX Locker type setup. I have a "thing" about things locking up when Im not expecting it.

:lol: like I mentioned in that thread….my pal Bill needs to be motivated with food. Got to keep treats in front of him like a dog to keep him focused :lol:

The verdict is still out on the ARB as the project is far from complete. I just got the axle under it yesterday afternoon and still need to set up the pinion angle and shock arrangement. I haven’t even gotten a compressor or air tank or even started laying out the front Bilstein 7100 shock layout yet. Got a long ways to go but I have until June when Desert Trip 2017 is booked.

The G-Van axle looks wider...My eye micrometer says about 1.5” on each side :smoke:

Re: Rear brake upgrade: 11” to 13”
 

Funny how you say that its wider. Does it even out with the front?

I had no clue that my old 60 was nearly 3 inches narrower than the front until I got the 14B home and found it was actually 5 inches wider than the 60. After the initial freak out subsided, I realized that it actually lined up the front / rear track a little better. 3/4" wider in the rear on each side.

I keep thinking that maybe if I keep some Oreos around, that the kids may help out a little more.... realistically though, Id end up needing an assplant :lol:

Cant wait to hear how the ARB works for you. If anyone would use it like its supposed to be used, it would be you.

Keep up the good work! Looks great!

true van width rear 14ff is 70" wms to wms . reg srw pickup rears are 67" and c&c is 64" . a dana 60 srw front is 69" .

Re: Rear brake upgrade: 11” to 13”
 

I'm going the other way, from 13 to 11 inch drums. I'd rather lose the weight than carry around a capability I'll never use. I'm swapping in a 14FF/dana 60 combo from a cucv into my 85 3/4 ton.

My only question is regarding the wheel cylinders. Are they different diameter/capacity and if so, does it affect the stock master cylinder?

Thanks for sharing the info Larry.

I went with discs on my 14bff so FREE to a good home 13"drums and backing plates. Of course you have to pick them up.

Re: Rear brake upgrade: 11” to 13”
 

Can anyone help???
I have a 1987 Chevy suburban 2500. It is a 350 gib with th400 trans. 4X4 it started life with a 9.5” semi floating rear. The carrier had a lot of slop and I had a 10.5” full floating rear out of another truck. Ever since I installed it the stopping power has been horrible. All of the rear brakes are new except drums which were cut and well within tolerance. I didn’t change the booster or master or proportioning valve. Also my truck still has the rear weight/level sensor and the brake lines do go through it. But they always did. My other two suburbans are a 1982 3/4 two 2wd. And I can lock it’s brakes up if I push the pedal too quickly. It is a 9.5”. Am I just expecting too much from the 10.5” brakes? Thank you in advance for any help or suggestions I really appreciate it. This is my plow truck and I’m trying to get it figured out before the snow flies. Again thank you!

first thing those load valves love to go bad and freeze up . by pass it .

then looking up the 87 burb master cylinder part #'s .

11" rear brakes was aluminum / plastic tank master with small bore size .

13" rear brakes was cast iron master with bigger bore for more fluid flow .

so if bypassing and bleading the rear dosnt help the next step is bigger master to match the bigger rear brakes .

but also double check the brakes are adjusted in the rear . self adjusters dont do crap most of the time . jack up the rear so tires are off the ground and click them up till just starting to scuff the drum face .
