New front pads and rotors for the eight-zero. I managed 35k out of Hawk Super Duty truck pads till they began squealing. They consistently warped the previous rotors. I went budget performance with the well-reviewed R1 Concepts slotted rotors, and semi metallic pads.
In keeping with the "upgrade the brakes before SAS 3 in Colorado" theme, I installed a new/remanufactured power brake booster. Unfortunately, this is the 3rd O'Reilly remanufactured unit my 80 has seen in 35k/6 years of ownership. Last chance, or I say screw the warranty, and buy a new Seiken unit from Cruiseryard.
Also, I switched over from Mobil 1 10W-40 to Shell Rotella T5 15w-40. Oil pressure went from approx 40 to 53'ish on the 'ol 3FE. It is marginally cheaper, and quieted the engine down a little bit.
Not bad at all. Takes about an hour on my 92. No need to remove the master cylinder either.How difficult was the brake booster? That's on my list.

More than likely that is the master cylinder, brake booster will result in hard brake pedal. From the FSM:Thanks. That's probably on tap for me this weekend. Brakes suddenly went very soft after a trip last weekend.

BRAKE BOOSTER ASSEMBLY
OPERATION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly. If the pedal goes
down furthest the 1st time, but gradually rises after the
2nd or 3rd time, the booster is air tight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed. If there is no
change in the pedal reserve travel after holding the pedal
for 30 seconds, the booster is air tight.
