# Braking Zones

> Understand how to read and analyze braking zone data for every corner in your laps.

**Braking zones** are the core of Braking Lab's analysis. For every corner in every lap, the system extracts detailed data about how you applied the brakes — from initial contact to full release.

## What Is a Braking Zone?

A braking zone is the portion of track where you slow down for a corner. Braking Lab identifies these automatically from your telemetry and measures:

- **Where** you started braking (distance from corner apex)
- **How hard** you braked (peak pressure)
- **How long** you braked (duration and distance)
- **How you released** the brake (trail braking characteristics)

## Zone Detail View

Select a lap and click on any corner to see its braking zone detail:

### Key Metrics

| Metric | What It Means |
|--------|---------------|
| **MRP (Maximum Reference Pressure)** | Peak brake pressure in the zone — your hardest hit |
| **Brake Application Point** | Where braking begins, in meters before the apex |
| **Entry Speed** | Speed at the start of the braking zone |
| **Exit Speed** | Speed at the corner exit |
| **Braking Distance** | Total meters from brake application to release |
| **Deceleration** | Average G-force during braking |

### Pressure Curve

The pressure curve shows how your brake input evolves through the zone:

1. **Initial spike** — The initial brake application
2. **Peak** — Maximum pressure (MRP)
3. **Trail braking** — Gradual release as you approach the apex
4. **Release** — Full brake release at or after the apex

A smooth, progressive curve indicates good brake modulation. Abrupt changes suggest inconsistency.

## Corner-by-Corner View

The corner list shows all braking zones in a lap at a glance:

- **Corner name/number** — Track position reference
- **MRP** — Quick comparison of braking intensity across corners
- **Entry speed** — How fast you entered each corner
- **Consistency indicator** — How this zone compares to your other laps

## Understanding MRP

MRP (Maximum Reference Pressure) is the single most important metric in braking analysis:

- **Higher MRP** = harder initial brake hit
- **Consistent MRP across laps** = reliable braking technique
- **Inconsistent MRP** = target area for improvement

The training exercises in Braking Lab use MRP as the primary target to help you develop consistent braking.

## Tips

- **Compare MRP values across laps** — A consistent MRP for the same corner means your braking is repeatable
- **Watch the trail braking curve** — Smooth release indicates good car control through corner entry
- **Entry speed matters** — If your MRP is right but you're slow, the issue may be how late you brake, not how hard
