Brake Pad Wear Trend Tracker (Fleet)
Log pad friction material thickness readings, see the wear trend and get a projected date when the 3 mm limit will be reached.
Readings stay in your browser (localStorage) โ nothing is uploaded.
Straight-line (least-squares) extrapolation of your logged readings to the 3 mm alarm threshold (warning at 5 mm). A low Rยฒ means the trend is noisy โ log more readings before trusting the projection.
Field notes from maintenance practice
For fleets the win is batching: project each vehicle here, then group axles landing in the same fortnight into one workshop visit. Measure through the caliper inspection window with a pad gauge at every service โ the same wheel, same pad, since inner/outer and left/right wear differently and the thinnest pad governs. The default action limit of 3 mm comes from common fleet/OEM practice of replacing pads at 3 mm friction material (legal minima are lower, ~1.6โ2 mm, but 3 mm protects discs and allows scheduling); adjust it if your OEM or procedure specifies otherwise.
Linear extrapolation is honest only when the Rยฒ is decent (โฅ 0.7) and degradation is steady. Pad wear per kilometre is fairly linear for a constant route profile, which makes the projection unusually trustworthy โ but a driver change or route change resets the slope, so segment the fit when duty changes. If the last reading jumps far off the line, re-measure before believing it โ measurement technique drifts too.

About Brake Pad Wear Trend Tracker (Fleet)
This tracker is a remaining-useful-life (RUL) estimator for pad friction material thickness. Log a dated reading whenever you measure; the tool fits a least-squares straight line through your history and projects when it will cross the 3 mm action limit (warning at 5 mm) โ turning scattered measurements into a forecast date you can plan parts and downtime around.
How to use Brake Pad Wear Trend Tracker (Fleet)
- 1Enter each dated measurement as you take it โ readings persist in your browser between visits.
- 2Adjust the alarm (and warning) threshold to your OEM or procedure limit if it differs from the default.
- 3Read the fitted trend, Rยฒ, days-to-alarm and the projected date โ then plan parts and downtime around that date.
Why use Brake Pad Wear Trend Tracker (Fleet)?
- โLog pad friction material thickness readings, see the wear trend and get a projected date when the 3 mm limit will be reached โ computed instantly with the standard formula
- โ100% free and unlimited, with no sign-up, login or paywall
- โRuns entirely in your browser โ readings and asset data never leave your device
- โNiche-specific defaults and thresholds for pad friction material thickness, traceable to the cited standards
Frequently asked questions
What limit should trigger action for pad friction material thickness?+
The widely used limit is 3 mm (common fleet/OEM practice of replacing pads at 3 mm friction material (legal minima are lower, ~1.6โ2 mm, but 3 mm protects discs and allows scheduling)). Set a warning at 5 mm so parts and labour are ready before the alarm. Your OEM manual or internal procedure overrides the generic figure.
Inner pads wear twice as fast as outer on my trucks โ is the projection still valid?+
Yes, if you always trend the faster-wearing pad โ it reaches the limit first and sets the service date. Uneven inner/outer wear that worsens usually means sticking caliper slide pins or a seized piston; fixing that both extends pad life and makes wear symmetric again, at which point your slope will visibly flatten.
How many readings before the projection is trustworthy?+
At least 4โ6 spread over a meaningful fraction of the asset's life, with a fit Rยฒ of about 0.7 or better. Two points always make a perfect line โ that is curve fitting, not condition monitoring. Keep measurement conditions (load, temperature, location) consistent.
Is straight-line extrapolation valid for wear?+
It is the standard first approximation for steady-state degradation, and it is deliberately conservative to act on. Many failure modes accelerate near the end (bathtub curve), so treat the projected date as the latest acceptable intervention date, not a promise.
Where is my logged data stored?+
Entirely in your browser's localStorage on this device โ nothing is uploaded to any server. Export or note critical values elsewhere if you need a permanent maintenance record shared across a team.
