    Default Engine braking

    Assalam o Alaikum brothers. I have a manual transmission toyota corolla se saloon. As you all know about it's bad brakes. I have made a habit of engine braking and brakes simultaneously. I mean if i am going at high speed and i have to emergency brake i downshift and the car goes at higher rpm and then i brake. In this way the car does not skid. I want to ask the gurus about the stress on engine and gears. Does this technique damage engine , gear , clutch or any other part. @Xulfiqar @capsat

    Frequently applying this practice is harmful to engine and as well as gearbox too,its better to take off your foot from accelerator pedal and press brake pedal slightly to reduce the speed ,during this period don't press clutch pedal,when speed reduced then press brake pedal fully and press the clutch only at dead slow speed.
    Never loose hope in life,every step gives u something.

    its not that harmful if you lower down gears one by one.like if you are going on 5th gear,and want to brake suddenly,lower to 4th,then 3rd depending on the situation...its harmful if you switch from 5th to 3rd on high speed because this will cause RPM to go boom..and while you are lowering down gears,keep using brakes too,that way both forces work together to stop the car

    Make it your habit to drive slow. Keep eyes straight on the road and start applying brakes from distance. I usually do not press clutch while braking after 2nd gear. Engine braking at higher speed increases grip on road. But I would never do what you do like shifting down to increase engine resistance. That will damage gears and engine at high speed.

    Engine braking is recommended, one should get used to it BUT excessive engine braking and shifting down too early is not good for the engine, drive train, engine foundations, axles and especially for the clutch. As clutch replacement is too costlier than brake pad replacement.

    I do engine braking carefully, not stressing the engine etc. and keep the rpm not more than 3000 on down-shifting. Plus one should not immediately press the clutch when brakes are applied, which means no engine braking. Anyone having idling issues will be in deep trouble while braking if the engine stalls....

    @saeedmagsi member @argtr65 have suggested very convenient way to keep vehicle in control ^5

    i beg to differ on your drive style, in a clear day over a city road speed shall be under 60 kph which can be controlled without over loading engine / transmission, over the highways line of sight have very large perspective and again high speed cruising can be managed without excessive load on motor & power train.

    please do some effort & try to drive with ease of mind and enjoy driving ,

    No problem with engine braking, as long as you downshift one gear at a time. In fact it will preserve your brakes, which is important.

    Downshifting should be done cautiously.

    Never downshift more than two gears at once. Your rpm will shoot up and it will effect your clutch.

    When you do want to downshift- always blip the throttle a bit, to match the rpms.

    So- 5th gear>clutch in>blip race>release clutch and you have matched the rpm. No extra stress on clutch, axle and engine.

    It's better to brake - less costlier.

    Turbo lag is like foreplay. You know it's coming. And it's gonna be good.

    Engine braking is a must on downhills. Basic rule is one should come downhill in the gear in which it can uphill. If you are able to climb in 2nd gear then you must come down in the same 2nd gear and the brake will assist along. This way you will save your brakes from overheating and lose control over it leading to critical situations...
