What trail braking actually is
Instead of finishing all braking in a straight line, you keep a small amount of brake pressure ON as you start turning the wheel. The brake bleeds off as the wheel goes on — they trade places.
Why it works
Light brake pressure during turn-in keeps weight on the front tires. Weight on the front = grip on the front = the car rotates. The moment you fully release the brake, weight shifts back to the rear and the front loses authority — that's when you understeer.
How to practice it in Forza Horizon
- Pick a road with two consecutive medium-speed corners (Mexico's coastal road, FH5 Tulum coast, or FH6's mountain switchbacks all work).
- Brake in a straight line as normal — but instead of fully releasing, hold ~10-20% brake pressure as you wind on lock.
- Bleed it off completely by the apex.
- Compare to your "normal" lap. The car should feel pointier, and you'll carry more speed mid-corner.
When NOT to trail brake
- Long high-speed corners — straight-line braking is faster, and trail can upset the car at speed.
- Wet surfaces — front tires are already overworked.
- Cars with extremely rearward weight distribution (mid-engine, anything with rear-bias brake setup) — trail-brake very lightly or you'll oversteer.
