Baku Turn 1 Braking & Lockup Telemetry Simulator

Driver & Brake Setup

Azerbaijan GP Lap 30

Braking Marker 118 m

Distance before Turn 1 apex where the driver hits 100% brake pressure.

Initial Peak Brake Pressure 98%

High initial pedal pressure at 345 km/h where peak aero downforce supports ~4.8G.

Pedal Bleed Rate (Trail Braking) Fast (0.75 s)

As speed drops from 345 to 110 km/h, aero downforce decays by 89%. Driver must release pressure or front tyres lock up.

Brake Bias (Front %) 56.5%

Higher front bias stabilizes rear entry but drastically increases front tyre lockup risk.

Street Surface Friction (μ) 1.50 μ

Baku street asphalt grip, painted zebra lines, and track evolution.

The Baku Turn 1 Dilemma

Arriving at 345 km/h after Baku's 2.2 km full-throttle section, drivers experience ~4.5G deceleration. Turn 1 is a tight 90° left turn flanked by unforgiving TecPro barriers and a narrow escape road.

Square-Law Downforce Bleed

Aero downforce is proportional to velocity squared (F_down ∝ v²). At 345 km/h downforce is ~28 kN; at 110 km/h it plummets to ~3 kN. If a driver does not aggressively trail off the brake pedal, the front tyres instantly lock.

Escape Road Bailout Calculation

Once a front tyre locks for over 0.35 seconds, flat-spotting destroys tyre integrity and turning torque vanishes. Lando Norris opted for the escape road runoff to preserve the car, dropping from P7 to P9 while negotiating the 180° spin-turn.
