Now 12 months on and another 2k miles it's failed again on rear brake corrosion and pitting.

 

I'll be fitting Pagid this time.

I guess that'll be a consequence of covering just 2k miles in 12 months, rather than the quality of the discs.

 

I noticed the rear discs on all 4 of my previous Yeti's became heavily corroded, unless I purposely stood on the brakes.

Indeed.

 

But for genuine Skoda £294,  Pagid at my local independent £160. I have Pagid on our Octavia which has done similar lockdown mileage and they have faired a lot better.

I never had this issue with any of the Octavia's I owned, but always found the Yeti suffered.

 

I did wonder if it related to the braking setup on the respective cars?

I did replace the rear discs on our Yeti as they were an advisory on the first MOT at around 15K and did look awful,  I do think however some MOT testers must be  failing discs with fairly superficial surface rust.  I would certainly try and get my discs "shiny" before presenting for an MOT.

 

On the Octavia front on my Mk2 (same "generation" as the Yeti) had scored rear discs as an an advisory on the first MOT, whereas on my Mk3 the rear discs look pretty good after 3.5 years and 34K.

 

To be fair however the Mk2 did live on the coast at that time, which may be a factor.

Not sure that discs can be failed on appearance, only if the vehicle fails the brake test, although a cracked disc makes me question that.

 

My discs were absolutely appalling, I had ordered new ones but they had not arrived, the tester who is an old friend was informed, it passed using a Tapley decelerometer for the brake test, I doubt they would have passed on the rollers.

I can't say for certain... but I think a (subjective) visual disc check for corrosion and pitting started being applied in the MOT about the turn of the century

This was on my Fabia with the same setup.
Rears get so little use corrosion is a problem.
The discs looked OK from what I could see except the inner pad was down to the metal.

Inside of my rear discs were just like that, the fronts were not much better.

 

Same year vehicle as well!
