stopping without using brake...

Its very simple--You upshift the faster you go, You downshift the slower you go and you apply the brakes to come to a stop.
Just a quick review : You upshift the faster you go, You downshift the slower you go and you apply the brakes to come to a stop.
Once again: You upshift the faster you go, You downshift the slower you go and you apply the brakes to come to a stop.

The biggest thing I that I hear all the time is, If you use the engine to brake...it will break. The drive train was designed and built to propel the car forward, not slow it down. Monitor the way the transmission works on an automatic. Your just cruising along, you take your foot off the gas and move it over to the brakes. Note, the revs. They will drop a few hundred rpm, then the trany will drop to the next gear. They never really go more then a few hundred revs.
But when you're in a manual, you can be doing 50mph and dump it in 2nd and the revs will fly up and you just take your foot off the gas. Not really a good idea IMO. Replacing brake pads > replacing a clutch.

This topic seems to pop up every now and then. While it's clearly possible to slow your Z down using engine braking, the most critical points are:
1) Whether rev-matching or not, the most accurate and effective way to stop or slow your car is using the brakes. PERIOD. Disc brakes remain the most powerful and effective braking system (in current mass production) for slowing and stopping your car.
2) The amount of wear and tear on both the engine and clutch will be HIGHER when attempting to use engine braking alone. Disc brakes convert motion to friction/heat with very few moving parts, in comparison to the reciprocating parts in the drivetrain.
3) It's clear that in high performance driving, being able to brake, clutch and downshift simultaneously, gives the competition or sport driver a distinct advantage. Executing a clean heel-toe downshift while braking HARD not only uses the brakes to their maximum, but allows the drivetrain to remain engaged and keeps the car stable. This method also uses rev-matching to allow the quickest acceleration off the corner as well.

is it possible? any disvantages of doing it this way?
thanks

you can stop a manual car without breaking but you will have to slow it down and let it roll to a stop on its own, just measure the distance and and feel the speed of your car and it can be done. its not the smartest thing to do but its doable. as someone mentioned earlier about being able to stop by stalling the car. im not sure if i got that right, but if you eventually end up slowing down in first on an even surface then you will not stall the car. you will keep moving forward with your feet off the gas and clutch just like an automatic unless you apply the brakes.
