Hi I just replaced the rear disks on our 2017 Yet at 18K miles as they were horribly corroded and the pads were 70% worn.  I am horrified that they needed replacing on such a new low mileage car but its does seem to be a recurring issue. We got the car last year approved used and the first owner was from the Carlisle area so I'm guessing lots of salt on the roads in wintertime and low mileage probably didn't help. I put Brembo on in the hope they will last a bit longer but it got me to thinking which aftermarket brands have lasted well compared to OEM discs in other's experience?

 

 

I'm pretty sure all Golf 5 platform cars are prone to rear caliper seizures

If you want to make your brakes last try this:-

Once a year in the autumn strip / clean and regrease all the brake parts.

 

Also make sure you use the brakes to stop them seizing up.

I occasionally apply the handbrake when moving to keep them fit and healthy.

 

Present car, rear brakes at 45000 miles with no rust and 8mm left on the pads.

 

Previous car, rear brakes at 13 years and 131000 miles on original disks, with no rust and one set of pads at 90000 miles.

 

Thanks AG Falco

I had the front brake pads and discs changed for the first time on TIBET III at 78k miles (5 years old) - they were down to just below 20%. Rear discs and pads are still original at 83k (6 years) - edges were corroded but were wire brushed to get rid of the loose stuff when I changed back to the summer wheels (and painted the callipers..).

Thanks guys....my 2017 Octavia I bought new is at 30K on the original discs and looking good....I think the damage was done to the Yeti before we bought it. 

 

So reading between the lines the consensus is that seized sliders are the issue rather than OEM disc quality?

juan, I too have a 2017 Yeti, & my Original discs are all but looking new.

As AGFalco says, a light touch on the H/B does wonders.

I'm not heavy on my brakes, & I normally change my car before tyres & brakes are needed.  😀

Lack of maintenance, not just the sliders.

 

I also make sure that the caliper pistons move freely.

 

As above a wire brush to remove any rust from the disks and slider areas will also help.

You will note from the photos that the rust creeps in from the outside edge and the middle on the disks.

 

I buy my cars new and keep them for a long time.

So I have more incentive to do this work.

 

Second car at 115000 miles / 11 years has had front pads at 45000 and disks and pads at 90000.

 

Thanks AG Falco

Do they really need changing as it is a well known con as rusty disc are only an mot fail if too thin but look like they need changing.

They tried to get me to change my rear discs at two years old last year due to corrosion but I declined. They are a bit scored at three years now but the car still brakes perfectly?

The discs in my pictures did pass the MOT a couple of weeks ago but I've never had discs in that condition. Pads would have needed replacing soon and I wouldn't put new pads on with those discs. 

If some of the face of the disks are rusty then this is because the pads are NOT pushing against them.

2017 Yet at 18K miles

 

Low mileage cars tend to get rusty disks more than regularly used cars.

I obviously understand that. However my brother has an 20 year old Mercedes E class that gets used quite infrequently (less than 5K miles/year) and is parked outside year round. Very little corrosion on his rear brakes. What I was looking for was advice on brake brands to achieve similar results with the Yeti. 

 

Audi use the same dimension disc on some models do they get better quality?

 

I have another Skoda of a similar age but higher mileage with no disc issues, but surface corrosion is very evident after a couple of days without use.

 

Whilst our Yeti was fairly low mileage I think it's first keeper living in a Northern hilly region of England with lots of salt on the roads in winter and also probably a month or two of little use when the car was returned to Skoda for resale will have been factors. May have been kept as a winter only car too. Who knows, but very very few keepers of a new car on a two year lease will do any "extra" brake maintenance.

I thought Rusty VAG discs was the norm. My VW 2004 Touran and 2014 Yeti both had light surface rust after a week or so. Now moved to Formby,Merseyside, 1/2mile in from the sea, my Audi discs are orange over night in the winter. Uncle with a new Merc and old Range Rover closer to the sea has no issues. It's all down to the steel used.

Since asbestos was removed from the pads I am aware that they do not last aslong, but still managed 72K on my Touran and when I sold the Yeti with 30K it looked like the pads on that would last a similar time. I'm also aware that discs are now viewed by many as a disposable/consumable item as they do wear far more quickly but cost a fraction in real terms of what they used to.

With 70% wear over 18K miles I also would be suprised and have looked elsewhere replacements.

Some pictures of my rear discs at 83k miles. Callipers painted, disc edges wire brushed and painted - might stop the corrosion, we shall see! Pads cleared the excess paint off (photos are as fitted, before use).

Whilst I appreciate the advice that with regular attention and use these discs can last, it's clear that the effects of corrosion are relatively bad on these.

 

I have a 44 year old SEAT 127 that has had the same front discs for the last 10 years+ despite doing really minimal mileage, parked outside and with zero maintenance. Front discs I grant you but the contrast is stark.

 

I think I read somewhere the OEM discs are Pagid? I'd certainly avoid those as replacements if you're doing less than average mileage and you aren't in the habit of stripping and cleaning your brakes.

 

To be frank if I have to put the car up on axle stands and strip the brakes every year to make the brakes last six years (say) l may be as well replace the discs every three years. 

 

Hopefully however the Brembos will fare better, time will tell.
