Lehman Monarch I on 2004 GW Do I have correct part #'s

[harrywing]

Looking to replace brake shoes, whl. cyl., and U-joints wanted to know if I have correct part #'s?
Brake shoes Duralast #569
U-joint Moog #430
Wheel cyls. Duralast #33825
Any help appreciated if u have additional #'s would also be interested. The Lehman manual as most of you know is not very helpful and calling was fruitless. I was on their website but part numbers weren't there
Thanks, Harry

Below is a copy of page from the 2003 book combined with my notes .... I forget which is which ... but your part numbers all look good. The brakes are Ford 9" diameter X 1-3/4 wide Ford drum brakes. Used on a huge variety of Fords from Pintos to Thunderbirds to Ranger PUs.

The wheel cylinders .... the Duralast 33825 is 3/4" diameter inside, but the ones that were on my '97 GL1500 / Lehman GTL solid axle that was triked in 1998 were 7/8" diameter when I measured them last year (I had one start leaking so I replaced both) so I used Wagner WCA79985 wheel cylinders. The larger diameter will increase braking effort slightly assuming same pressure applied at foot pedal, but they also result in slightly more pedal travel to apply. I think that maybe Lehman revised their choice to maybe shorten pedal travel after 1998 but before 2003. Either number will work .... or there is a very slight, almost non existent chance that mine were replaced with the larger ones between 1998 and 2004 .... but knowing the owner / builder / dealer and knowing him since 1998, he'd have R&R-ed with exact same WCs as come off.

I may well replace mine's 7/8" WCs with the slightly smaller 3/4" diameter WCs myself ..... been thinking some on it this coming winter just to see if I like the change.

(7/8" diameter area 0.6013408 sq in)
(13/16" diameter area 0.518503 sq in)
(3/4" diameter area 0.441786 sq in)

… ETC …

Can't edit now. It should read "The larger diameter will increase braking pressure (how hard the shoes are pressed against the drum) slightly assuming same effort (call it "muscle power") applied at foot pedal, but they also result in slightly more pedal travel to apply." Just wanted to clear it up

Note: substituting smaller wheel cylinders will slightly pressure seen at the shoes assuming same effort applied at the pedal.

Carry on …. Merry Christmas!
