Mom and dad should have been working on the installation Xmas morning in the driveway :-)
Very nice gift. Nothing like the gift of stopping well.

 

For the 3" shoes, do you know how many shoes the Napa part # contains? I'm trying to get an idea price wise. My local Napa lists the 3" shoes for 67.36, but they don't say how many that price includes.

 

Some good info and ur a lucky guy brandon!

 

The $63 Price i think is for a set of 4 shoes? Mine came all in 1 box oddly enough.

I got mine at my cost though, So i don't get a receipt unfortunetly, boss is real weird

 

Thanks. If that's the case then new 3" brakes with all the drums and hardware will be fairly cheap.

 

Drums are $85 a Piece i think?

 

hey-Hey!!!,
On the brakes, there are two reasons to worry about area of the rear cylinders and the two effects are opposite each other. First is based on volume required to move the shoes. The two master cylinder pistons move at the same time, so a bigger rear cylinder means you'll put more pressure on the fronts for a little while with bigger rears... On the bigger cylinder, once you've got contact the bigger piston inside will take what ever brake line pressure and exert more force on the shoes.

So, in my 1990 I have yet to wish for more rear brake power...ever. So bigger wheel cylinders would deliver more front pressure while the rear was taking more volume to begin pressing on the shoes. I just don't know the slope of the lines, and when/if they'd cross and have the set-up with bigger wheel cylinders deliver more( unwanted ) braking force.

As I understand it, the stockers on my D250 are 1" cylinders and 2.5" shoes. 1.125" cylinders may find themselves on there at some point...'specially if I get a believe-able answer on just exactly how they'll work.
cheers,
Douglas

 

What kind of drums are they?
Last time I had to get a rear drum it was on a Sunday and the only kind he had was a Chinese one.

I want to keep BUDD drums on the rear.

They are from NAPA and say Made in Usa on the label......

 

Did you successfully remove the ABS valve?

 

Nah don't need to. Brake pedal is nice and high, not mushy and the truck stops good and straight AND the rear brakes don't lock up. The D250 we used to have, the PO did a ABS Valve delete on that and in the rain the rear brakes would lock up very very easily. Scary

 

Did you have to special order those cylinders? I just tried to get some at Oriellys and they said I have to see a manager during the day because it's special order. This was an orielly warehouse store and usually has everything.

 

Sounds rediculous. At Napa I just looked them up by 91 W350, then went under wheel cylinder and looked for the one that said "3 inch Shoes 1 1/8 Bore"

ALSO, if your truck is a Single wheel DO NOT get axle seals for a W350 !!! duallies use a bigger seal and a bigger "spindle", A duallies is .303 vs. a SRW .287....a dually axle seal will slide right over and not seal anything! You will need to know this when you buy seals and if you buy speedi-sleeves

 

Thanks, I already have my seal part numbers from replacing one a while back.

 

I see some discussion here about front brakes applying strongly before the rears take hold. There are 2 reasons why that happens, or maybe 3 if you include excessively large rear cylinders. I suspect, though, that cylinder size has minimal effect on the phenomena.

1. As DOT3 fluid ages, it picks up moisture and other contamination, and gets thicker or even sluggish. It's more apparent id there's any ABS equipment involved. It needs to be changed (flushed) once in awhile.

2. If rear wheel adjusters don't work properly, the extra shoe to drum gap will cause a delay in actuation.
