All clutches require a run in / bed in period.
How long does it take to change a clutch? Generally changing a clutch can take anywhere between 2 to 6 hours. If you book in for the job, we recommend you should put a whole day aside just in case. Like with any other repair job, the length of time taken varies due to a number of factors.
Never abuse a newly fitted clutch. Allow 500-mile break-in and always adjust free travel on your new clutch at 750 miles and again at 1500 miles. Approx. time for the break in mileage is two full tanks of fuel.
If you don't push the clutch in, the cars engine keeps pumping power to the wheels and drive train, which keeps the wheels spinning, which defeats the purpose of hitting the brakes.
There is no break-in period or protocol, per se. It is a good idea to use the clutch lightly and avoid heavy loading for a short period of time. The flywheel and pressure plate are machined and the new disc will wear-in to that surface in a short time.
When you first purchase a car, moving the clutch and changing between gears should be effortless and smooth. If, after a while, you notice that changing gears becomes more difficult and you feel a grind when you shift gears or put your vehicle into reverse, this could be a sign that your clutch needs replacing.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong. Don't get left at the side of the road with a vehicle that won't shift into gear. Read on to learn the signs and symptoms of a failing clutch.
While braking, you should always depress the clutch.
This is one of the most common scenarios wherein people do apply the brakes but forget to disengage the clutch in-turn stalling the car. Well, stalling the car especially with transmission load will take a serious toll on your vehicle's gearbox assembly.
Many drivers will do this by holding on to the clutch biting point to keep themselves steady on the incline. But, by doing this, you're burning up the friction material on your clutch disc as the clutch will be spinning at one speed while the engine's pressure plate is moving at another.
In answer to your direct question, YES, worn clutches will cause a loss of acceleration, the springs wear out as well as friction material, so the clutch discs don't 'clamp' down as hard on the flywheel.
Turn the engine on in neutral and allow it to run until it heats up. Push your clutch pedal and blip the throttle a few times. The expeditious shift in engine speed and the heat coming from it can potentially cause the friction disc to break loose.
At High Speeds: First brake then clutch
Brake is first used when you are travelling at decent speed and you need to slow down a bit. Now, if you decide to stop or the speed of your car reaches the lowest speed of the gear then you would need to use the brakes so that your car does not stall.

So to change the clutch, you have to separate the two, which is a fairly big job. As such, it may mean the engine has to be lifted, or dropped lower depending on the car, to make enough space to crack the gearbox and engine apart. This takes lots of time.
The trick is to let the clutch out to the engagement point quickly and then more slowly from there. The only way you can know where this engagement point is, is by getting a feel for the car.
If the clutch is released quickly, the transmission, which is stationary will apply opposite force and the clutch will wear off much quicker than normal usage. Releasing the clutch quickly can also do serious damage to the transmission.
Whenever a driver pushes down on the clutch, there's a large amount of strain that is placed on one part of the car, the so-called release bearing. After enough time spent at red traffic lights, all this pressure on the bearing can lead to significant damage.
If you have a manual transmission, you SHOULD always put the car in neutral and leave your foot OFF the clutch when stopped at a light. Those with manual transmissions should also remember to apply the parking brake before going for pizza.
If you press the clutch and accelerator at the same time, your engine will be disengaged from the drive train and it'll rev up and make noise, but that's all - it won't do any damage.
The proper way to slow down your manual transmission-equipped car is to downshift. When you take your right foot off the brake, you press the clutch with your left foot, shift down a gear. You will have to touch the accelerator pedal to do some rev matching before releasing the clutch.
In general, you'll want to keep this rule of thumb in mind: the lower the gear, the more power you have available. The higher the gear, the faster your engine runs! With both manual and automatic transmissions, you'll generally move from lower to higher gears as you accelerate.
Let off the gas and let your car slow down a bit. Then press the clutch, downshift, and ease the clutch back out. If you time it right, you will feel a firm but smooth deceleration. Continue through enough gears to slow down to the appropriate speed – or until you are ready to stop.
The shift becomes another part of the body for the driver. Nevertheless, clutch replacement is necessary after every 40,000km to 100,000km or more, depending on various factors.
Your clutch feels spongy, sticks or vibrates when you press it. You hear a squeaking or a grumbling noise when you press down on the pedal. You can rev the engine, but acceleration is poor. You have difficulty shifting gears.
