HYDRAULIC BRAKES Hydraulic brakes operate according to Pascal's law. Pascal's law explains that the pressure exerted on a liquid in a vessel is equal to that on the inner surface of the vessel. Construction  The diagram above shows a hydraulic brake system. The master cylinder is connected to the caliper on the front wheel by steel pipes and to the wheel cylinder on the rear wheel. Flexible hoses are also used in the brake circuit to accommodate the movement of the axle. Working When the driver presses the brake pedal, the master cylinder compresses the fluid and delivers it through pipelines to the rear wheel cylinders and front wheel calipers. The fluid reaching the wheel cylinders pushes the pistons to either side. This movement of the pistons pushes the brake shoes ourwards and activates the rear brakes.When the fluid reaches the front caliper, it moves its piston and friction pad against the disc and activates the front brakes. Most of the vehicles use hydraulic brakes as

TROUBLES ON CLUTCH 1. Clutch slip This is manifested in the clutch engage state. The clutch is unable to transfer all the torque generated by the engine. As the clutch slips, more heat builds up, causing the clutch face to wear out and ignite. 2. Clutch drag Clutch drag is a condition in which the clutch does not fully disengage when the clutch is disengaged and it is difficult to change gears. 3. Clutch judder This is a defect that causes the clutch to engage with vibration and shaking when the clutch is engaged. For this reason, the vehicle accelerates rapidly. 4. Clutch rattle When the clutch is engaged, the noise coming out of the clutch is known as rattle. This is most evident when the engine is running at idle speed. ക്ലച്ചിൽ ഉണ്ടാകുന്ന തകരാറുകൾ 1. ക്ലച്ച് സ്ലിപ്   ക്ലച്ച് എൻഗേജ് അവസ്ഥയിലാണ് ഇത് പ്രകടമാകുന്നത്. എൻജിൻ ഉത്പാദിപ്പിക്കുന്ന ടോർക്കിനെ മുഴുവനായും ക്ലച്ചിന് കൈമാറ്റം ചെയ്യാൻ കഴിയാതെ വരുന്നു. ക്ലച്ച് സ്ലിപാകുന്ന സമയം കൂടുതൽ ചൂട് ഉണ്ടാവുകയും, ക്ലച്ച് ഫേസിങ് തേയ്

COMPONENTS OF A CLUTCH 1. Clutch plate The main component of the clutch plate is a steel plate with a central hub. Friction liners are provided on both sides. The coil spring receives the torsional vibration of the clutch and prevents it from entering other parts. The clutch faceplates are secured with specially designed cushioned springs to reduce the impact of the clutch while engaged. There is a possibility of torsional vibrations during clutch operation. The clutch plate is made in two parts to eliminate this. It is the central hub assembly and the outer facing ring assembly. Both of these are connected to each other using coil springs in specially made slots. 2. Clutch facing It should be low wear and high friction and should be able to withstand high temperatures without clutch facings and can be manufactured at low cost. The main materials used to make the clutch face are leather, cork, phobic, asbestos, rabatos and ferro. 3. Pressure plate & clutch fork The pres
