For the practical test, the Tell Me/Show me question :- He says:
"Tell me how you would check that the brakes are working before starting a journey"
What you have to do :-
Brakes should not feel spongy or slack. Brakes should be tested as you set off. Vehicle should not pull to one side.
For the practical test, the Tell Me/Show me question :- He says:
"Tell me where you would find the information for the recommended tyre pressures for this car and how tyre pressures should be checked."
What you have to do :-
Manufacturer's guide, use a reliable pressure gauge, check and adjust pressures when tyres are cold, don't forget spare tyre, remember to refit valve caps.
For the practical test, the Tell Me/Show me question :- He says:
"Tell me how you would check the tyres to ensure that they have sufficient tread depth and that their general condition is safe to use on the road."
What you have to do :-
No cuts and bulges, 1.6mm of tread depth across the central ¾ of the breadth of the tyre and around the entire outer circumference.
CHANGING A TYRE WHEN IT BURSTS
You must stay calm, do not panic!
Slowly take your foot off of the gas and let the vehicle coast to a stop.
Do not make any sudden braking or steering actions.
Put your hazard lights on to alert other drivers.
Now that you are safely off of the road you can go about changing your tyre
Tyre Changing Step 1: (Stopping)
Make sure you are on firm flat ground and sufficiently far away from the traffic. If you are not, then try to drive to a more suitable spot, but only if you can do so safely. Try to avoid driving back onto the road and into traffic.
Tyre Changing Step 2: (Safety First)
Make sure your handbrake is on and put the car in Park or 1st gear if you have a manual transmission. Ensure that the engine is turned off.
Tyre Changing Step 3: (Tools)
Locate the spare tyre, jack, and wheel wrench. These are usually located in the trunk underneath the carpet on cars. Trucks usually have the jack and wheel wrench behind the seat or under the hood, with the spare tyre under the bed.
Tyre Changing Step 4: (Instructions)
Typically there are instructions printed on the jack or somewhere near the storage compartment. Read these instructions, they will tell you where to jack the vehicle and any special steps you will need to take.
Tyre Changing Step 5: (Getting started)
First remove the hubcap or wheel cover. The wheel wrench often has a flat end, which you can use to pry off the cover. If not, a screwdriver will work just fine.
Tyre Changing Step 6: (Lug Nuts)
Before you jack the car up you will want to break loose the wheel nuts. The weight of the car will keep the wheel from spinning and allow you to apply more force to the nuts. You do not want to completely remove the wheel nuts yet.... just break them loose. Once the wheel nut begins to move, STOP and move onto the next one. I often carry a small pipe, which will fit over the wheel wrench. This pipe can provide additional leverage and allow you to get those stubborn wheel nuts off. Always remember righty tighty, lefty loosy. Turn the wheel nuts left or counter clockwise to loosen.
Tyre Changing Step 7: (Jack the car)
Now you should be able to jack up the car. Locate the manufacturer jacking points by reading the owners manual or the instructions near or on the jack. Most cars will have a reinforced lip where the jack can be placed. If you can not locate this, look for a solid portion of the frame to jack on. Make sure the jack is on firm level ground and start jacking. Take it slowly and only go as far as you need to get the wheel completely off the ground.
Tyre Changing Step 8: (Remove Tyre)
The wheel is off the ground and it's time to remove the wheel nuts. Use the wrench or your fingers to remove the nuts. Slowly take the wheel off and set it to the side.
Tyre Changing Step 9: (New Tyre)
Get the new wheel and put it on the car. Tighten the wheel nuts as tight as you can without the wheel spinning. Don't worry about getting the nuts super tight, as you will do the final tightening when the car is off of the jack.
Tyre Changing Step 10: (Jack the Car)
Let the car down off of the jack and get your wheel wrench. Tighten the wheel nuts in a star pattern if there are five nuts. Start with one wheel nut and skip the next one until they are all tight. If you have 4 nuts, just tighten the opposite nut from where you started and then the remaining two in any order.
Tyre Changing Step 11: (Wheel Covers)
Replace your wheel cover or hubcap and clean up the jack, wheel wrench and blown tyre. If your spare tyre had air in it, you should be able to continue your journey. You may be organised enough to have a tyre pump that runs off of the cigarette lighter in your car. If you do check the tyre pressure that you should pump to and inflate the spare tyre accordingly.
Finally: Remember if you have a temporary spare tyre (AKA doughnut) you can only drive a few miles to a service station and usually not over 50 MPH.
At least every week check the tyre pressure (including spare). Incorrect tyre pressure may adversely affect tyre life and vehicle handling. Tyre pressure should be checked when tyres are Cold after the vehicle has been parked for three or more hours, or driven less than 1 mile. COLD tyre pressures are shown on garage forecourt. Different vehicles have different tyre pressures so check the charts.
Insufficient pressure can lead to overheating of the tyre and subsequently internal damage. At high speeds, this could result in tread separation and even bursting of the tyre.
Tyres should also be inspected for wear, cracking, bulging, or objects caught in the tread. If excessive wear, cracks, bulging, or deep cuts are found, the tyre should be replaced.
Most new tyres have a built-in tread wear indicator. When wear indicator is visible, the tyre should be replaced.
In the UK by law, Cars, light vans and light trailers must have a tread depth of at least 1.6mm across the central three-quarters of the breath of the tread and around the entire circumference.
An easy way to check the tread depth of your tyres if they don't have wear indicators is with the use of a 10 pence coin. Place the coin in the tread and make sure the tread covers the edge.
