Electronic Parking Brake Usage

[Nyrjoe]

New to the CX-5 and EPB. Read through the thread and I'm still not clear, is correct use of the EPB for it to be used instead of shifting into Park? So for example pull into a spot, depress brake and while still in D engage EPB then shift into park?

Always have CX-5 in Park (preferably) or Neutral when engaging EPB.

Never engage it when in drive. That is what Auto-hold is for (used at traffic lights etc)

Xeler8ing, thanks but earlier in this thread there is a how to link which states the following (It is best to engage the parking brake while the brake pedal is being depressed, before shifting into park this will reduce the strain on the parking pawl). This seem to go against what you are recommending, maybe I'm just not getting it?

When you come to a complete stop, keep pressing the brake, put it in park (or neutral) then engage EPB. After this you can depress (let go) the brake.

Been doing this for over 2 years on my 6 and not an issue.

It really makes no difference what gear the tranny is in when you engage the EPB. But you REALLY SHOULD keep your foot on the brake until the EPB is engaged. That is what prevents the strain on the pawl-- keeping the car from moving and putting pressure on the pawl before the EPB is engaged. It has nothing to do with what gear you're in.

But here's something this thread made me wonder about: can the EPB be engaged while the car is moving? I don't have the courage to experiment to find out! Has anyone ever tried it??

EPB should turn on automatically when shift is in P. I assume it doesn't?

I've noticed a few times that the EPB has engaged automatically when I shift into P, but only when auto-hold is on [I don't use a-h all of the time]. It always surprised me. But it seems to be inconsistent. I'm going to pay closer attention to this.

Has anyone else noticed this behavior?

EPB in some cars automatically disengages if you forget to when taking off

Yes, shadonoz, I've noticed this as well. After using autohold and then restarting the car later, the EBP is on sometimes. Haven't quite figured that one out yet as well. As for engaging the parking brake while driving, I believe I read in another thread that it can be done in case of brake failure when driving. You pull up on the button and hold it up for the EBP to engage. An errant pull up of the button won't trigger it, it has to be a deliberate effort.

Yup, the 2017 Mazda CX-5 does. Not a feature I like, however; not smooth enough.
And interestingly, it won't auto-release if your seatbelt isn't fastened. Smart and safe.

I read that, too, but I really wondered if anyone had tried it in a CX-5.

Found this in the pdf Anchorman kindly uploaded [EPB (1).pdf]:

Emergency braking function
The electric parking brake can be applied while driving the vehicle. Braking force is generated and the rear wheels
are controlled so that they do not lock-up only when the electric parking brake is pulled up while the vehicle is
being driven.

AND

Note
The emergency braking function operates only when the electric parking brake switch is continuously pulled
up while the vehicle is being driven.
If the accelerator pedal is depressed while the emergency brake function is operating, the emergency brake
is released to give priority to vehicle acceleration.

AND

Note
For vehicle speeds of 5 km/h {3 mph} or more, independent anti-lock control on the left and right is
performed so that the rear wheels do not lock-up.
When the vehicle speed is 4 km/h {2 mph} or less, the emergency braking function does not operate so
that the system can determine if the vehicle is about to stop.
So you've got to pull it up and hold it, just like the old handle. But alas, no fun.(drive2)

That’s good to know. The trick is to hold the switch up for emergency braking.

The parking brake does disengage automatically if driving but i think it’s better to disengage it manually and not rely on the auto function.

(iagree)

An interesting observation today. When driving home from work, I was stopped at a stop light. I was using auto hold as is normal on my commute. Since I knew it would be a while before the light changed, I removed my seat belt so I could retrieve my gloves from my coat pockets and the EBP automatically engaged. Must be a safety thing where the car detects your seat belt is not fastened and applies the emergency brake when the car is in gear.

 

[Xeler8ing]

Sounds like it

I’ve been told that emergency brakes are prone to freezing. I’m wondering if the Mazda engineers have overcome this possibilty. I’m thinking that their concentration on the “non freezing” electric brake may have distracted the engineers from developing auto electric windows all round.

I always use when parking, anywhere out of habit.

Also USE IT IN RED LIGHT WHERE I KNOW THE DARN LIGHT IS FOR A LONG TIME. The best part of EPB is its instantly released as soon as I press gas.

 

[bmninada]

The EPB came in with the 2016.5 facelift. This is mine in April last year just after it had been backed off the delivery truck. Not a handbrake lever in sight! BTW, they movie guys only need to pull the ABS fuse just like they do now and they can perform all the tricks they like.

It came with 2016 in CX5. I know since when I bought my CX5 the sales guy was going Gaga over it.

 

[bmninada]

You know another thing about EPB: you wont see any more folks pushing up and down the parking lever rapidly while in park to tighten the rear brake drum!!

BTW: can there be EPB and drum brakes?

 

[Pipemajor]

Flat or incline, above or below freezing, I always engage the parking brake whether it be electronic or manual. The EPB will spoil you in that you don't have to release it before moving. It disengages automatically. Might lead you to forgetting to do so when using a vehicle without it.

I also tend to use the auto-hold feature a bit more these days.
