Binding rear near side brake.

[kiakid2]

Here we go again – nearside rear brake slow to release when moving from stationary – after a replacement set of discs / calipers was fitted in December 2017 under warrant 17,000 miles later the problem seems to have reoccurred ……………..

I have just had this issue as well on my 63 CX5. MPG dropped over the weekend but figured it was DPF related as had done a lot of short journeys. Cruising along the motorway and car started juddering, got out and found smoke bellowing from NSR wheel. Mazda now advising it needs 2 new calipers and RAC warranty refusing to pay as they say it will be cause by corrosion and therefore not covered by them.

Anyone ever got anywhere with Mazda outside of warranty as seems a very common problem...

Also does not seem to be any aftermarket calipers as far as I can find, anyone know of any?

The earlier models with no Emergency brake are very easy to work on. 2 bolts out to replace the pads, 2 more if you need to change the discs. You also need something to screw the piston in, preferably a proper one which is not expensive. Plus HT lubricant so the pads can move freely. Even at home a maximum of 2 hours work to change everything. £1,000???
