The correct braking technick varies. As far as I know, this subject is not covered in DCS manual.
Moreover, braking efficiency is related to the touch down speed.
The whole story starts when you are in final approach. There you will have to define at first which is the right approach speed, taking in account current weight and wind. A good way to define the approach speed is to configure your A/C (gear, flaps) and maintain level flight (flight path marker on the horizon) slowing down up to the speed that the Angle of Atack indicator shows the Green Circle. This is the speed that you will have to memorize and maintain when you start your final glide path. Of course there are other parameters, such as crosswind and turbulence, that you will have to take in account in order to avoid any inconvenience (stall).
Unfortunately, the DCS manual doesn't cover this subject. A nice and safe rule is the following.
Add to the ideal speed, provided by the green AoA symbol, the half of longitudinal (head)wind component and the turbulence strenght.
1st example: 20knots headwind and 123knots ideal final approach speed. The final approach speed should be 10+123=133knots
2nd example: 20-30knots headwind and 123knots ideal final approach speed. The final approach speed should be 10+10+123=143knots
2nd example: 20-25 knots from 30deg from right or left, 115knots ideal final approach speed. The final approach speed should be (cos30°*20)/2+5+115=(0,866*20)/2+120=128.66knots.
So, if you keep a final approach of 2.5-3° and you maintain the right speed then the only you will have to do is to aim for a white line touch down and then you will have to brake aerodynamically (nose high attitude) up to the speed of 80knots. Don't forget to engage Nosewheel steering and you will find out that you will need thrust to taxi up to the nearest cross section. Moreover the use of airbrakes is very effective.
Try it guys.
