Working of Layout of Hydraulic Brake System – Brakes and Dynamometers – Theory of Machine

In this video we will see the working of the hydraulic brake system so here I have written the topic name it is actually the layout of hydraulic brake system in layout I would be describing how the hydraulic brake system is constructed that is how it looks like so if we can see here in this diagram which I have here we have one two three and four these are four wheels and as we can see in one wheel we are having one internal expanding brake next in the second wheel also third and fourth wheel in all the wheels we are having internal expanding brake also called as drum brake next as we can see here here the piston and cylinder arrangement which is provided in each of the internal expanding brake that is connected to a master cylinder so if we are looking into the construction part of hydraulic braking system hydraulic brake system consists of master cylinder inside which we have piston and spring then this master cylinder would be actuated with the help of brake pedal here brake pedal will be moved about this pivot that is pivot is a fixed point about which the brake pedal will move then after that we have for internal expanding brakes there is wheel cylinder after that through the master cylinder there are pipe lines which are going into each of the internal expanding brake then here we have brake drum and brake shoes for the internal expanding brake so this was in brief the construction of hydraulic braking system now how it works the working depends on the brake pedal here we are having a brake pedal if we are applying the force on this brake pedal by applying the force means when we are pressing the brake pedal with the help of the foot lever in that case when it is pressed here we are having a piston master cylinder would be free with brake fluid also called as brake oil so since the medium is hydraulic hydraulic means it uses oil and that oil is nothing but brake oil so when we are pressing the brake pedal through the linkage that is the P mode the brake pedal it will move the piston in the forward direction when the piston moves in the forward direction it will be compressing the brake oil which is filled in the master cylinder so the pressure of the oil rises now that high-pressure oil will go into the channels which are provided it will go into the two front wheels it will go into the two rear wheels once the hydraulic oil passes in one of the wheel it will be pushing these Pistons these small small Pistons are there so the brake oil will exert the force on each of the piston and when the force is exerted on the piston here we would be having pivots and about the pivot this brake shoe would be moving outward and when it moves outward it would be coming in contact with the rotating brake drum and hence the braking action takes place so similarly it will happen in each of the wheels just by pressing one brake pedal we are able to actuate the brake in four of the wheels that is the vehicle would be stopped it would be stopped just by pressing the brake pedal and it is very much understood that when the brake pedal would be pressed oil passes through each of the cylinders simultaneously and all the wheels they would be stopping at once it is not as such that oil will go into the first cylinder it would be stopping first then second third fourth know when the oil would be coming it would be passing through all the cylinders at the same time and then we are getting the braking action so this was regarding the hydraulic brake system
