I have traced the source of a power steering leak to the “Hose Pump to Booster” line as shown on Figure 5-69. The poor brake performance was traced to the master cylinder.
CaddyDaddy hose SKU 76PE91566 has the following specs:
Hose End Type 1 - 3/8 inch Male Inverted Flare
Hose End Type 1 Thread Size 5/8 inch - 18
Hose End Type 2 - 7/16 inch Male Inverted Flare
Hose End Type 2 Thread Size 11/16 inch - 18
Approximate hose length - 53 inches
Gates hose #364040 shows the same sizes in decimal form.
The CaddyDaddy ad states to “compare to yours to ensure proper fitment”
Even if I take apart the fittings in my unheated garage, I have no way to confirm thread size and count.
Has anyone used this part and if so, was it a direct replacement?
For the master cylinder, CaddyDaddy SKU TEMNMC M2072-1 is listed for the 1976 Cadillac Commercial Chassis but has the same “compare yours to ensure proper fitment.”
Attributes shown are:
#of line ports: 2
Brake Master Cylinder Bore Size: 1 1/8"
Brake Master Cylinder Line Thread Size: 9/16"-18, 1/2"20
Primary Outlet Thread ½" 20
Secondary Outlet Thread 9/16" 18
Has anyone used this part and if so, was it a direct replacement?
For the master cylinder, rebuilding is not an option as my mechanic lacks space to store the ambulance. That being said, I will retain the old part for a possible future rebuild.
