Question about emergency brakes

[Oldengineer]

I noticed that my new CX-5 uses a lead screw rear caliper set-up as an emergency brake. Has anybody had problems with the emergency brakes sticking on in cold snowy weather?

Haven't had any issues yet. I use it every time I park.

I use it when I park, and when I am on a dirt road and want to make a cloud.

Going into my 3rd winter, manual transmission w a sloped driveway. Never a problem with freezing.

It never stuck all winter long last year down to -35C, and I use it every time I park.

tsk tsk tsk. looks like some of you winter parking brake users aren't following the owners manual

 

[erhayes]

I use mine all winter haha.

I never leave my cars parked without setting the parking brake. Even in the cold, rain, and snow since my CX-5 is not kept in a garage. No issues with seizing brakes, other than a slight pad and rotor lock up after a long sitting in moisture, which is normal.

Thanks folks for the info. My CX-5 sits outside too. The reason I asked this question was I once had a Jaguar X-Type that used this type of parking brake, and, I had to keep the crank arms and cables on the back of the calipers greased up in the Winter.

Not surprised since the Jag X-Type was based on an old (90's) Ford CD platform and shared many parts with Ford's. They weren't exactly reliable back in the days LOL.

Yes, there is a groove in my rear brakes indicating drag from the emergency brake (so says the mechanic) caused by corrosion. It is going to cost me over $400 to fix.

That could just as easily have been caused by a foreign object, a rock for example, being wedged in a brake pad over a period of time. Usually you can hear it but on a rear... perhaps not.

$400 to perhaps resurface rotors and replace pads? Holy s***, your mechanic blows.

I had 2 of the X Types - a 2.5 Liter 2003 and a 3.0 Liter 2006 Model. They were actually 80% Jaguar and 20% European Ford Mondeo. Yeah - they both had niggling problems that required too many trips to the dealer for warranty work, but, they were a blast to drive. The Toyota MR-2s had the same problems with the rear emergency brakes as the Jags did - liked to stick on in the Winter.

Actually, the $400 was for new rotors and pads. Now it appears that MZda will cover at least some of the cost dut to the wording in the TSB. Still waiting on word from Mazda.

Please show me where it says in the owners manual that the CX5 has an emergency brake? The CX5 and just about every other modern vehicle today employ parking brakes, not emergency brakes. There is a big difference! Parking brakes are only meant to hold a stationary vehicle at rest from rolling down a hill or stationary. They were once called emergency brakes eons ago but auto manufacturers smartened up on that one and changed the name to parking brakes.

I guess one could call antilock brakes emergency brakes too.
