Brake fade: the drums and linings are overheated past the point where friction works — the pedal feels normal and the truck barely slows.
Heat, not wear, is the immediate enemy: an overheated brake cannot grab until it cools
Smoking is the visible stage; the next stage is a brake that does almost nothing
The engine brake and a lower gear are the systems that prevent it — service brakes are for speed corrections, not for holding a truck back for miles
Get off the throttle, use the engine brake at its highest effective setting, downshift if speed allows, and aim for a runaway ramp or a wide pullout if speed is climbing.
A runaway truck ramp is a tool, not a punishment — use it before you need it
Apply the service brakes in firm snubs (brake to drop a block of speed, then release) rather than riding them
Riding the pedal is what built the heat; more of it will not save you
Park it, chock or hold position safely, and let the brakes cool fully — do NOT set the parking brake on overheated drums.
Setting the spring brakes on hot drums can weld and warp components and lock the wheel when it cools
Do not pour water on hot brakes — cracked drums are the usual result
Walk-around from a distance: look for a wheel still smoking, a tire heat-checked or melted at the bead
Only after a real inspection of the hot wheel ends — glazed linings, cracked drums, and cooked seals do not announce themselves from the driver's seat.
A brake that faded once on this grade will fade again on the next one if the cause is adjustment or load distribution
If one wheel ran hotter than the rest, that wheel's brake was carrying more than its share — that is a repair, not a cooldown
Tell the dispatcher which wheels smoked — the pattern tells the mechanic where to start
Start the descent in the gear you would need to climb it, engine brake on, at a speed you can hold without the service brakes.
Brake in snubs: firm application to shed speed, full release to let the brakes cool between applications
Know your weight — a heavy load on a long grade is a planned descent, not a surprise
Some corridors have grades that punish riding brakes — local operators in those areas see this failure pattern weekly
