Should You Engage the Handbrake or Shift to P First After Parking?

[McBrianna]

After parking, you should shift to P first and then engage the handbrake. The correct method to engage the handbrake is: 1. Press the handbrake button while pulling it up; 2. Apply gentle force when pulling the handbrake; 3. The handbrake should be engaged to about 70% of its full range—pulling it all the way to the top will shorten the lifespan of the handbrake cable. The function of the handbrake is to provide braking when parking on flat ground or slopes, preventing the vehicle from moving unintentionally and avoiding traffic accidents. The dangers of forgetting to engage the handbrake include: 1. The brake pump may fail to provide sufficient braking force, causing the engine to stall; 2. Accelerated wear of the brake disc and hardening of the brake pads due to friction heat; 3. Stretching of the handbrake cable; 4. Potential leakage of brake fluid, leading to brake failure.

Last time at the repair shop, the mechanic said this is quite particular. For automatic transmission cars, after coming to a complete stop, first press the brake firmly and shift to N (Neutral), wait until the car is completely stationary, then engage the handbrake tightly, release the foot brake to transfer the braking force to the handbrake, and finally shift to P (Park). The mechanic pointed at the transmission and said shifting directly to P can jam the parking pawl gear, especially when parking on a slope, the transmission gears will be under stress. With accumulated metal fatigue, that positioning pin will eventually fail. I've been doing it this way for three years, and the transmission hasn't made that 'click' noise during hill starts anymore. Remember to straighten the steering wheel when parking on a slope, in case the car rolls, it can catch the curb.

Lao Zhang, a taxi driver with 15 years of experience, told me that pulling the handbrake in a manual transmission car is instinctive, while it's more confusing with an automatic. His old Passat, which has run 400,000 kilometers, has developed a habit: after coming to a complete stop, he directly shifts into P and then pulls the handbrake. Actually, parking on flat ground doesn't make much difference, but once on a slope at Ciqikou in Chongqing, he forgot to pull the handbrake and relied solely on the P gear. The loud 'clunk' when shifting out of gear when retrieving the car was painful to hear. Now he's learned his lesson: when parking on a slope, he always pulls the handbrake first, then releases the foot brake, and only shifts into P after the car slightly settles. Placing bricks under the wheels is also a rustic method, after all, repairing the transmission could cost half a year's worth of fuel money.

The ramp in our residential underground garage is extremely steep, and the property management has posted a notice advising to 'engage the handbrake before shifting to P'. Initially, I found it troublesome and always shifted directly to P, until one time when there was a loud 'clunk' from the transmission while shifting. The mechanic explained that parking on a slope with just the P gear puts all the vehicle's weight on the gear teeth. Now I've developed muscle memory: stop with the brake pedal → the electronic handbrake button clicks and lights up → release the footbrake to let the car settle naturally → finally shift to P. Following this sequence makes the gear shift incredibly smooth when retrieving the car. Cars with auto-hold are even more convenient, as a firm press on the brake pedal automatically engages the parking brake.

Parking on slopes is truly an art! Last year at the steep slope of Badaguan in Qingdao, I stalled and as usual just shifted to P without engaging the handbrake. The next morning, the gear lever felt welded in place—I had to yank it out with force, accompanied by a screeching sound. The dealership said the transmission pawl was jammed too tightly, and prolonged use could lead to gear teeth damage. Now I've learned the proper way: On slopes, first shift to N, engage the handbrake, then slowly release the foot brake. Wait until the car's slight rocking stops before pressing the brake and shifting to P. On flat ground, although it's more flexible, I always engage the handbrake first, letting the brake pads rather than the transmission bear the vehicle's weight.

My cousin who works in mechanical design once drew me a force diagram: The P gear is essentially a positioning pin inside the transmission that inserts into the gear slot. When parking on a slope, the entire vehicle's weight presses on this pin, leading to accumulated metal fatigue and potential breakage. He demonstrated the standard procedure: After coming to a complete stop, keep your right foot on the brake, then engage the handbrake first—this transfers the vehicle's weight to the braking system. When you release the foot brake, the car may shift slightly, indicating the force has been relieved. Only then should you shift into P gear, leaving the transmission solely responsible for preventing the car from rolling. Extra caution is needed when parking in snowy conditions during winter—forcing the car out of P gear when the wheels are frozen can damage the gears.
