Installing Rocky Mountain brakes...

[oldmotorsguy]

...on a 1925 Model T Roadster with a 1926 engine and ******. A few questions before I order the kit:

1. The kit specifies which year it fits: do I order the 1926-1927 year kit? Or since the wheels and hubs are 1925, do I order the 1909-1925 kit?

2. When welding the extension onto the brake pedal, can this be done without removing the pedal, (or engine, God forbid)?

I have committed to doing this for a guy, and have estimated 6 hours labor, how far off is this estimate? I work slow, but steady...

The kit is mated to the size of brake drums. IF you have 26-7 drums then order that kit or vice versa.

Doug:
This 1925-registered car is an amalgam of pieces and parts: it has the 21” split rims with balloon 4.40 x 21 tires. Where would I measure to determine if it also has ‘improved’ brake drums (26-27), rather than its original 1925 drums?

The Improved car drum is 11 1/4" dia, the small drum is 8" The RM kit for the '26-'27 uses the std Ford drum. The other RM kit comes with a new big drum. If using the std Ford drum, remove any paint from the outer edge surface where the RM brake shoe will ride.

The pedal tab could be welded in place, but its easy enough to remove the brake pedal after securing the band ears with wire tie. You have to adj. the brake pedal to have it come on after the RM sets the rear wheels. So the inspection plate on the hogshead will come off anyway.

Add some install time for the road tests too. Adjustments will be needed.

Tmodelman:

I've never removed a pedal so far, but then again, I've never needed to, either. What's involved? Removing the hogshead inspection cover, wiring the ears of the brake band together, removing the nut, grooved washers and spring. Does this pedal just slide right out of the driver side of the upper hogshead? If that's the case, I may just bill the guy to buy a pre-welded brake pedal (about $140 or so), and be done with it. I've seen them online.

You also mention add some time for adjustment on the road. I've already billed (and received) 6 hours labor @ $95/hour. I've set the guy up for the possibility of additional hours: do you think I will need them? In other words, is this an all day job?

The other day I put a set on my 27 Roadster. Went very smooth and they work very well..
