My rears do the same Deeps, as for burning off during summer I think you agree that's a load of rubbish. I sometimes drive slowly for a 100 yards with handbrake just applied to clean up one the old one, but no remedy for EHB version

My Kia Sportage was the same and to overcome this I used to regularly apply the handbrake to clean the rust etc.


No, I think that you're misunderstanding my post kiakid2. The effect that you are describing can often be observed on vehicles that have been left stationary on the dealers forecourt for a period of time i.e. surface rust on the discs which can be removed by the method you describe namely running with the brakes held on for a while. Brake cleaner will also do the job without leaving an oily residue.

However, the running with the brakes on method relies on the pads being parallel to the discs so that the braking effect is spread evenly across the entire surface of the disc.

The latter is NOT the case with my CX-5 and neither is it with a lot of other users from what I am reading. Here it would appear that for whatever reason the pad is either grooved in some way or is not set up parallel to the discs or it's something to do with the calipers I don't know. The end result though, is that only part of the pad is making contact with the disc creating uneven concentric circles along with relatively deep scoring although this is not easy to ascertain from the image as it's not in 3D LOL.

Unfortunately, with the electric handbrake, that can’t be done on the Mazda, so I try and use the car any time I see rust spots forming on the disc, in an attempt to reduce the corrosion aspect.
I am the laugh of the street when I cover the wheels when the car is not in use for 2 weeks or so in the winter

I've got those and I think they do have more grip in the wet than the Toyos.

Agreed!

Wheels & Tyres / Michelin Latitude Sport 3
« Last Post by CX-Fiver on January 18, 2018, 12:55:27 pm »
Got a nail in my NS Front tyre the other day and as both front Toyo Proxes were pretty worn out, I decided to replace both, rather than have the puncture repaired.

After a bit of Googling, I went with 2 x Michelin Latitude Sport 3 from Kwik Fit at £325.25 fitted. Not cheap but no-one could do 'em cheaper, especially as Kwik Fit have a free mobile fitting service if you buy 2 or more tyres. It's a really good service this and I recommend it - wouldn't go to one of their centres though.....

Anyway, the Michelin's are excellent with loads of grip in the wet, which is where you want it most obviously. Don't think there's any difference in road-noise but they do feel more stable and compliant over bumps than the Proxes. Mind, the Proxes were well worn, so the Michelins should be better across the board.

Interesting, we had some posts about this back in March 2017 when I needed new pads and rear discs

Steering/Suspension/Brakes / Rear brake discs rusted/heavily scored
« Last Post by Deeps on January 17, 2018, 03:07:22 pm »
I wonder how many forum members have looked at their CX5's rear brake discs recently and noticed the uneven wear across the width of the braking surface? I first noticed what I believed to be an issue in early 2017 when it was noted that the discs (both sides) had alternate bands of rust, shiny surface and heavy scoring. When pointed out to the dealer during a routine winter > summer tyre change it was stated that this was probably caused by road salt particles becoming trapped between the discs and pads and that prolonged braking over the summer period should see the wear return to normal i.e. a complete shiny disc as is the case with the front brakes.
 
However, this has not been the case and in fact the situation has deteriorated to the point that only approx 50% of the available disc surface is actually making contact with the pads whilst the remaining 50% of disc is completely rusty and this has occurred despite the fact that the vehicle has not been in contact with any salt etc at the time of writing this. Further more, the scoring cannot simply be put down to a stone becoming entrapped between the disc and pad resulting in the scoring because the deterioration on the N/S matched exactly that of the O/S.

My own opinion is that the rear brake setup has been badly designed as with a lighter vehicle but especially so with a relatively heavy SUV it should be the front pads/discs that wear first as the physics of the braking motion places a greater braking force on the front hence the larger discs up front.

Anyway, without further rambling (sorry) this problem is well mentioned over on the German forum and receiving mixed results from Mazda (Germany) by way of response. Some vehicles appear to have travelled considerable distances with rear and front discs/pads showing acceptable wear all things being equal whilst some low mileage cars (older as well as new models) being indicated as suffering exactly the same problems of unequal wear/scoring as mine which has only travelled some 15,340km and is just over 2 years old. From what I read, Mazda's response has fallen far short of consistent as repairs have been carried out against the guarantee or goodwill in some instances whilst in others they have put discs/pads down to being wear and tear items thereby not falling within the scope of the guarantee. Photos have been taken by the dealer in my case and I am currently awaiting a response from Mazda (Germany). It will be interesting to see upon which side the coin falls in respect of my claim. Should I have to replace the discs/pads at my own cost (they won't pass any MOT in their current condition) then I shall seek to have the old items returned to me and take legal advice.

You must be located in Germany as I am Mike. Remind me please, how long has this saga regarding the blue sticker been going on for now LOL. And with respect to 'hardware' updates - well that summit of all summits in Berlin not all that long ago didn't see much motion in that direction. Good old Winfred :-)

Steering/Suspension/Brakes / Re: Electronic handbrake

The electronic handbrake releases automatically so no need to hold on the foot brake. Just pull away as normal and the handbrake will release automatically.

Hill hold assist is useful if you haven’t engaged the handbrake. Holds the car on a hill for 2-3 seconds allowing you to pull away without rolling back.
