Erm, is corrosion like this normal on rear brake discs

[ultra_joel88]

Noticed this on my passenger side rear brake disc today.

Other one is fine....

Is this normal?













If not can someone point me in the direction of replacement OEM discs/pads OR a well priced disc/pad combo.

Whichever is best really.

[L-Y-K]

i think mine look like that though im in need of replacing them real soon so i think im gonna get some upgraded breaks saw some on ebay with grooves! they looks nice!

taking a closer look i dont think i've lost that much metal...

[Skodaboy1983]

Hmm never really looked at my rear discs, might be worth a look later.

[vRS Dovit]

ouch! that dobt look good, joel

That is one heck of a lip.

Are the discs still above minimum thickness? That size of that lip suggests they are probably not to me.

If they are a still good in the swept area, then get out a wire brush and some fine wet and dry.

Wire brush the large rust off the edges and then just run the wet and dry over the exposed surface a few times to get it smooth so you don't damage the pad from any sharp bits left.

If the discs are close to their minimum thickness then I'd probably just get new discs anyway as they are fairly cheap. 312mm vented fronts are only £60 for a pair from GSF so solid rears would probably be in the region of £30 for the pair

EDIT: Yes rust on the unswept parts of discs is perfectly normal

[ultra_joel88]

I checked the thickness and it seems they are above the 7mm minimum.

But they dont look too healthy. Reckon they are daffy ducked?

[Shifty]

Standard discs are not to pricey, and pads from skoda are £15 iirc. Not a big job. Mine went like that too. The rear brakes do virtually nothing on the Fabia from my experience.

[cheezemonkhai]

You could clean them up, but it depends if you value your time.

If you value your time highly, then a new set of discs and pads will probably cost the same as the hour and bits spent cleaning those up.

I think if it was me I'd get the wire brush and give it a going at. while still on and do half, turn the disk and do the other half. If it doesn't improve it quickly I would just get some new ones.

Seen it on other cars too but as Dave said the rear brakes don't really do much so this is not unexpected.

[ultra_joel88]

In the end I've got some Mintex OEM replacements off ebay, pads and discs for £40

[ap0gee]

Mine ended up like that after about 40k, and was advised to get them replaced because they'd have been an MoT failure had the car been up for its test at that time. The ZeroSixties I got instead seem to be in much better state considering they've been on for a good 20k now...

(Although what with the brakes being over-servoed as ever on modern cars, they and the Mintex Extremes made for some, erm, 'interesting' moments on the way in in the sleet this morning... That or the Pirellis - am beginning to wish I'd stuck with the Toyos )

Anyway, back on-topic, I wouldn't say they were 'normal', because they shouldn't really get that tatty, but it's definitely not uncommon on the Furby...

I would have thought that a good time to upgrade to TT brakes.

Good to hear it didn't cost you the Earth to fix though Joel.

[Wardy]

These are rear brakes Vista, there aren't any worthwhile upgrades for the rears.

As Dave said, they don't do a lot and tend to corrode. Not seen any quite as bad as that though

Not on the back mate.

They are underused as it is on the fabia, so putting bigger brakes there will mean even more problems.

The Mintex OE replacement you've got should be just fine assuming it's the real deal

[ap0gee]

...plus the vRS uses the same rear discs / calipers as the 2WD TT did anyway...

[TKW]

I wouldn't bother cleaning them up as you might taking more corrosion off one side than the other and end up with an unbalanced disk.

Either leave it, if it's above mon thickness, or replace IMHO.

One of the MOT items my Fabia failed on a few years ago was the rear brakes - excessively pitted.

It does happen, they aren't used that much, and in my case, the pad usage was all squigly matching the pits and grooves of the disc.

In the end, I just changed the lot - discs and pads were around £50 for a complete set.

If you do decide to change yourself, you'll need a windback tool because the brake pistons rotate on a corkscrew thread as they come out. I did write up a guide about it

Last point: it's worth checking both wheels - again, I had / still have uneven wear from one side to the other and the handbrake is a bit dodgy because the calipers seem to get "stuck" sometimes and not release properly when you drop the handbrake.

This is a very interesting thread. Can I ask what sort of driving you chaps who've had rear disc corrosion problems do? I do 44 miles per day on country lanes. I'm just awaiting a Fabia 3 with ESP so will have rear discs brakes. Is this issue associated with low mileage around town or with cars used for average/above average mileage on faster roads too?

I'd problems with brakes in the past and was told part of the problem was that I was being too light-footed on the brake pedal and to brake more firmly on occasions to keep everything healthy.

How often do Skoda recommend brake fluid changes? On the Vauxhalls, I changed mine annually.

The other thing I've noticed is that the tyres fitted as standard on the Fabia 3 are W-rated and good for up to 168 mph. It seems a bit excessive on a car with a maximum speed of 109 mph!

I do 15-18000 miles per year; mostly on motorways. But then I wouldn't be braking very often on the motorway, so it's not necessarily a good thing in terms of preserving the brake discs... I have non-Skoda discs on now, which seem to be lasting a bit better, but then I also have fast road pads which might help get the discs hotter???
