      Using more of the front brake is definitely the ideal way to stop a bike.. but only on ideal / perfect roads.

      On our less than perfect desi roads this practice sometimes proves to be dangerous (speaking from personal experience). The loose desi surface (gravel/stone/sand/soil) on our roads makes locking of the front brake as easy as ABC.

      From my personal experience, a 50:50 front and rear brake distribution is the best on our Indian roads.

      I have locked the front wheel many times and have spilled on the road twice just because I am yet to overcome my habit of using the front brake more.

      Hi friends,

      Recently I bought the Karizma ZMR. I've ridden the ZMA-R quite a lot, so I was confident of pulling it through with the new one too.

      But I have observed this thing twice, whenever I brake hard at speeds around 50-60, the rear portion skids. Thankfully, I never fell off. I use both discs for applying brakes.

      I didn't notice this problem with Karizma R or with Pulsars (drummed ones).
      Is my braking technique faulty?
      My Braking Tip: Engine Braking + 50:50 front & rear brake application

      The best way to brake and yet remain in control of the bike is NOT to pull in the clutch lever while braking. Pulling in the clutch lever
      frees the wheels from the engine.. just drop the accelerator and brake (50:50 front & rear according to me) by NOT pulling in the clutch lever.

      By not pulling in the clutch, lets the engine slow down the bike and lets one remain in control of the bike. This is also called engine braking.

      Just before the bike is about to come to a complete stop, one can pull in the clutch so that the engine doesn't stall.

          Use rear brake paddle with moderate pressure, that's the max limit. But front brake can be used with different (increasing) pressure.. It all depends upon the grip levels.
          And always try to keep your bike and handle straight & vertical while braking, this way wheel lock will not make you fall.
          and do learn breaking..

            Just keep trying to brake well at slow speeds and soon you will become master of it.
            And never push the rear brake lever hard as you used to do in a drum brake bike.

            Slight push to rear lever and two fingers for front brake are good enough to stop the bike without skidding.

              Even Drums lock up easily.thats how the rear brakes are.Front is what stops you,the rear is used only to slow down.always use both the brakes like.70%front and 30% rear. just practice and you will get used to it.

                Bike Skidding is always the problem in Panic braking. very hard to learn that technique in panic braking. i always brake properly when i am riding fast because i know to control or maybe i am in control of my bike, but i have fallen when i am riding slow or average speed and suddenly something comes in the front of me. i always have mix riding style. now i am more careful while riding and try to control my braking. lets see if it works. anyhow no major damage been done to bike or me as well whenever i have fallen. so allz well till now.

                  The purpose of my original thread is that guys on here will obtain the videos, try the techniques and discuss the contents, very little feedback is there though!
                  Wow.... I saw The Street Smarts series (a 3 video collection). Its a must watch for every biker i feel. Everything has been explained in detail. I loved the braking and counter steering lessons. Thanks for the advice bro....

                    Bread is known to be extremely addictive. Subjects deprived of bread and given only water, actually begged for bread after just two days !
                    Bread has been proven to kill. Scientists have now uncovered alarming evidence that 100% of the people who eat bread will eventually die !

                        Am I the only one to think 80 front and 20 back or any kind of bias on the front is absolutely dangerous.... I mean, one can control a back wheel skid, but you can't control a front wheel skid....!!!!

                        1) mix in engine braking
                        2) dont pull back on the clutch while braking, it creates a free roll of the wheel and doesnt decrease momentum, instead if u let go of the throttle, the engine braking kicks in, and u can hit the front and rear brakes simultaneously - about 25 percent of both...


                        also, learn how to skid, as in practice skidding on purpose - the rear wheel - that way, when u do skid, ull know how to react and control the bike.

                          Well, after watching plenty of videos and tutorials and comments from racers, I can say 80-20 combo seems right... I mean when all pros say so, then it must be right! Moreover, a front skid is highly impossible... If you don't brake when leaning over (in a bend/a corner), the front won't lock up. Hence no skid. Plus, its our duty to ensure that all gear changes and braking are done before making the turn to a corner. In a corner, we must roll on smoothly throughout!
                          Apply brakes only when the bike is upright, not when tilted!!! [For sudden braking while in the mid of a corner, straighten ur bike, apply brakes - mainly front (80-20) and continue....]

                            I have Pulsar 180 UG4. I don't know whether my rare drum brake is weak or I am weak to break it with my feet. The rear brake responds only if I push hard on the lever with my toe. Infact I apply both brakes 50%-50% at the same time but maximum response is from the front disc brake. My bike is 3 years old. Do I have to replace the rare brake ? What is the price of it ?

                            I fell few times of which one was very bad that left me with scratched pilot lamp, dome, broken foot peg, torn pant and shirt and sprained ulna bone in the wrist 2 and half years ago. I learnt a lesson on that day that not to be hard on brakes on rainy days especially while cornering or bending or zig zag the bike.

                              Be it drum/disc, rear brakes are always softer than front!
                              That's the reason you see smaller discs on the rear as well.

                              Have you replaced your rear drum brakes (drum brake pads) ever in these 3 years? If not, maybe you best change them to new ones.
                              They may have glazed out with prolonged use.
                              Also, maintain 70:30 :: Front:Rear braking ratio to avoid any spills.

                              I started this thread last year and trust me I have learnt a lot and still there's a long way to go.
                              I used rear almost 90% of the time and the bike used to skid/fishtail like crazy.
                              Slowly I learnt proper braking and followed the 80:20 method. Now it's more like 70:30 as I suggested you above.

                              Rules of thumb:-
                              1. Follow 70:30 front:rear combo.
                              2. Never brake hard in a corner.
                              3. Use your rear brakes more than the front when riding in sand/gravel.
                              4. Service your drum brakes and the disc brakes periodically.
                              5. Make some use of engine braking when halting from high speeds.
                              6. Avoid pulling the clutch lever when braking.
                              7. Practice panic braking. A parking lot would do.

                                Sharan, whatever brake percentage we apply our natural instinct will match it before someone teachs us? Whether someone already
                                said or not I don't know but after the fall I learnt to keep the left foot ready to touch the ground before any hard brakes.
                                Most of us do this but don't observe these natural ways.

                                In the above videos the 2 different riders were differently thrown off the bike and amazingly they missed the fall.
                                Is it a new kind of stunt or is it our body's natural way to save us ?
                                Shown below is a very interesting video of replacing rear drum brakes.

                                Is it the rubber that gets damaged around the new gold colour drum brakes that he replaced after years ?
                                What is the price for Pulsar 180 UG4 drum brakes ?
                                I like to do it but I have to buy those tools.
