driving style question - using the electronic hand brake

is it a bad idea, while still in Drive, to apply the EHB when the car is stationary e.g. at red lights? or should you change gear to Park instead? or just hold it with the foot brake?

My understanding is the electronic brake is designed for exactly that, pull up to the lights...apply foot brake...apply electronic park brake and leave in drive. Simply apply a little gas when you are ready to move off and hey presto.....bloody good idea in my book and I use it all the time.

Well done LR for such a useful bit of kit.

I might be wrong but am not sure that it is quite good idea to apply EHB when in dirve as you said Daz.
Looking at it from my perspective simply because of the clash which both comands generate causing bit more wear of bits and peaces on transmition and breaks.
Personaly, I just put neutral when waiting on lights and so can not harm anything. Thumbs Up

For a bit of fun.......try pulling it up at 30mph, works a treat, but make sure you've got your seat belt on.

Did it first at a L.R. experience day in one of their cars, isn't as dramatic as you think!

Ish. 'Surprised' .

There is absolutely no substitute for a genuine lack of preparation.

Also make sure there are no other cars following you because it works amazingly well at hauling such a heavy car to a stop! 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Thats because when you are moving at speed it applies ALL the brakes of the car as an emergency brake so it uses the full braking capability of the car.

And yes, it is a dramatic demonstration that you do on the LR experience day.

Really? Where did you hear that, can't seem to find anything in the manual on this.

From what I see, the EPB applies brakes which are inside the rear drums only, they don't apply the rear disc brakes, so how would it electronically apply the front disc brakes?

Just be aware that if you have your foot on the brake pedal whilst in neutral you are also energising the solenoid in the gear lever (knob) - which might not be a good idea if its for a long period. If you use the EPB whilst in neutral, that's fine. Malaysia Boleh!

Paul, it's the miracle of electronics... If you pull the parking brake lever at any speed above 6 mph, the EPB module will electronically request the ABS module to apply brakes to all four wheels. When the car comes to a complete standstill, the hydraulic pressure from the ABS module is released and the parking brake engages normally on the rear drums. It's called "Dynamic Braking". The system is very sophisticated: During dynamic braking for example, the EPB module also monitors the deceleration ratio through the wheel speed sensors, and if for any reason (because of a defective ABS module, complete hydraulic failure or faulty CAN bus communication between the two modules, all of which would cause ABS not to operate as requested) it detects that the car is not slowing down at a specific rate, it automatically engages the parking brake shoes instead, so you will still come to a stop eventually, just not as quickly. Very Happy If the ABS module works but is unable to apply brakes - e.g. because of hydraulic failure - the EPB will actually "use" the ABS module and sensors to apply the parking brake with anti-lock on the rear wheels, and still turn on the rear brake lights in the process! Pretty amazing.

Mlines - my hats off to you for that esoteric knowledge. This could definitely go into the thread of "things you didn't know about your RRS"...

Umberto - fantastic description as always...how come I can't find this in the manual, this must be information reserved for moderators only! Very Happy Very Happy

The funny thing is I just recently had to have my EPB cleaned since I had gone thru some very nasty stuff that wouldn't come out with a normal cleaning, and when I applied the EPB, it sounded like I was killing a cat... PJPR

There have been a couple of TSBs issued in this respect and I think there was one issued this January.
Basically it says that the causes of this 'screech' is that the brake shoes are corroded, worn or incorrectly adjusted.This will cause excessive lining wear and/or noise and heat. If this has been going on for awhile, the internal components of the EPB actuator may have over-travelled and may be jammed. Unnecessary operation of a jammed or over - travelled EPB Actuator should be avoided. Malaysia Boleh!

So what is really the proper way then when waiting at the lights?

Coko, don't worry.

Normal traffic lights, just leave it in D and hold the brakes.
If you feel the wait will be very long then just shift to N and apply the EPB, no need to use the foot brake. Wink Malaysia Boleh!
