it generates the most g's on a racetrack what am I talking about breaking of
course and that's what we're talking about today on the Racing Line
but where do you brake well right here in the brake zone these breaking markers
give you a reference so you know just went to slam them on when is that exactly when you
start to see the bright white of the pearly gates break market's leading into
the corner give you a reliable reference to hit the same exact break points every
time every lap without markers can be difficult to find an exact breaking
point for you to find your own a skid mark a crack in the pavement a crime scene
rough neighborhood so how late is too late when I hurts your exit speed exit speed
is king or to state the obvious if you end up in the wall the wall is not your friend
now we need to talk about antilock brakes ABS has been around for the last
couple of decades and in every new road cars for years but there somewhere
isn't always allowed that's racing some serious emphasize human driver control
over the computers so if you're going to be a racer learn the ins and outs of
racing with ABS and without first I'm going into a foot to the floor panic
stop with ABS then I'm gonna do the same without ABS and we'll see what happens
with ABS
ABS is easy you just jam those brakes on computers do all the work working and they quickly turn the
brakes on and off without ABS as you can see from the results
ABS stop the car much faster than the car without ABS but using abs still
isn't the best way to stop and we'll get into that later let's do that again but
this time I'll try to steer with my break to the floor
avoiding this wall of cones
cone navigation with ABS great thing about yes that you maintain steering control like
this is the car will still turn he even under heavy braking cone navigation without ABS
without ABS no matter what we do with the wheel we'll still go straight as you can see in on ABS car
locks the tires continue straight on no matter how much steering you give
the other hand with ABS engage the car's computer adjust breaking so the wheels
keep rotating and steering can still happen and this leads us to the Tire
Rack minute tires grab best with just a little bit a slide too much and they'll
lock instantly losing bite losing steering response and possibly ruining the tire
the flat spot like we've done here just flat spot throughout a race this is only
going to get worse to tire will tend to lock up right there on that same place
flat spots will hurt your lap times they ruin a tire and if you haven't
figured this out tires win races for what we learned so far the first rule of
break club is to not lock up your tires so what is the best way to break
well there is no one best way it depends on the situation and there are different
types let's start at the Max threshold breaking
a threshold break is right on the edge of the ABS it's the strongest way to stop
the car on track it's when tires develop their ultimate bite with just a bit of
slip this type of breaking is the most common and reserved for breaking when
straight and balanced as you can see threshold breaking stops just a bit
faster than full abs and way faster than locking up the wheels without ABS so
threshold breaking can stop and a shorter distance what's the point of ABS
on track
well if you go just over the point of threshold the ABS is there to make sure
you don't flat spot the tires and lose steering even for professionals can be
difficult to break perfectly at the threshold every time brushing the break
what's the problem with threshold breaking heartbreak transfers a ton of wieght
forward unbalancing the car sometimes a brush break is all that's needed to
balance the car for the turn
a brush break can be good mid corner very lite breaking point the nose and it
transfers way to the steering tires and improve their grip trail braking
break hard and straight and then as you turn a lil trail off the pedal this is erasers bestfriend
because it loads the front tires helping the car steer the tighter the turn the
longer the trail break because as soon as you go to the gas the front
gets lite and the car straightens out left foot braking automatically CTS and
quickens the time to get to the brake pedal it may only be milliseconds but that's what wins
races emergency braking and finally say it's lost control spun out you got no
idea where the cars going next
what's the best thing to do take your hands off the wheel sing Jesus take
the wheel Jesus take the wheel
no this is the time to lock 'em and lock em hard and get that clutch in too make
sure you remain predictable and don't hold back on the track with the rest of
the field barreling down upon you on that note break late break hard and
don't break yourself driving enthusiast and will see you next time on The Racing
Line I'm at Road Atlanta racing a sportscar 152 miles an hour down the back
straightaway I go to the brakes and I get a hard pedel but no brakes are not very much
and I thought wow and I drove the car sideways cash the dirt underneath the
bridge come out from under the bridge
upside down in the air and I'm thinking to myself I could end up in the hospital
on this one and I get
