If i do so, is it good to press the brake without pressing the clutch... pls suggest me a clear answer...
Yes, if you press brake gently and release immediately the car will slow down.
The slow down will come from the lack of accelerator pressing not the braking. The clutch is not needed until speed drops to the point where a lower gear is needed. Half of newer drivers on this forum want to use the clutch too much, half can't use a clutch at all.
Yes of course pressing the brake is going to slow the vehicle. However with a manual transmission as you slow you need to gear down, as I'm sure you know. No, you do not have to press the clutch when you press the brake in,.. but if you are slowing a great deal , it would be wise to hold the clutch in while braking (and if you have the coordination gearing down (letting the engine help brake, as well). Why? Because if you are in, say, 4th gear.. at 45mph -- and you need to slow down to 15mph -- the car will bog down and might stall out by just pressing the brake and not the clutch (which is essentially neutral) -- then selecting the proper gear when done braking.
