993 front discs psychoanalysis

[Orangecurry]

Obviously it's me that requires the psychoanalysis.

This is a follow-on from my 'has anyone tried Brembos on the 993' - I tried to get some at a ridiculously cheap advertised price, but (after ordering) were told they were not currently available - so I bought the Sebros again from ECP/carparts4less for about 120 GBP delivered for the pair.

I fancied the Brembos as they advertise a special glossy UV coating on the hats that withstands time/salt/corrosion and still looks fab years later. The Sebros just have grey paint.

I have some Brembos on the Subaru, since 2014 and have done 60k miles on them, and unbelievably still show almost no lip... and the hats still look like new if I ever cleaned them, which I don't.

The old Sebros on the 993 hats paint is now grubby and worn - oh the shame. I can't even bring myself to photograph them.

Anyway - the Brembos came back available for a RIDICULOUS price, so I bought some anyway.



You can see the Brembo coating process is more sophisticated than the Sebro painting - which looks like they paint the whole disc (properly) but then sand the paint off of the faces.





Manufacturing looks identical (both discs weigh 8.1kgs)



Brembo has marks stamped in the hat



Sebro has no marks, other than a useful L and R.



...but the Sebro wins on packaging... do we care?

Management Summary

Manufacture looks the same, weight identical, I'd choose the Brembos every time on their hat-coating process.

The RIDICULOUS low price is simply icing on the hat.

Hey PP.

When looking for parts, I always look at ECP/CP4less (same company) and GSF to start with (then Autodoc etc etc), and it was GSF who have the ridiculous offer price... but they are now out of stock again.

I wonder if the Indies buy up all of the stock when it's on offer like this?

GSF may come back in stock (for home delivery) if you keep watching.

Many thanks OC,

I don't actually need any right now, but will keep a look out for pricing and buy when they are cheap.

I think some of these sites also operate some sort of surge pricing algorithm.

All good - but as GR says, they are available again. Same ridiculous price. I mean seriously. Buy some to keep fruit in, or to throw at next-door's dog when it barks late at night..

[Orangecurry]

I'd keep trying.... first attempt at purchase I also was given a refund... almost before the money had been taken, which was good. So very little chance of being left out of pocket.

Let us know if you spot any cheapos

They are 80 GBP on Autodoc at the moment - however, the Pagid version are showing as oddly cheap on ECP, but my 993ness won't let me have different makes of disc front to rear - stupid I know.

This might be a silly question, but you dry your brakes??? How do you even do that?

He means he drives the car after washing, gets the brakes to do some work, and the heat generated will dry discs/pads/calipers.

GSF are showing as out of stock for me, but fingers crossed.

Not found anything for the rears, but not constantly looking

For the record, I got the Brembos for the rear from Autodoc. Best price I could find for a pair that matched the fronts. They were £157 delivered for the pair, which feels like a rip-off, but only because of the ridiculously low price of the front discs from GSF!

£253 all in for discs and pads all round doesn't feel too bad to me. Callipers don't look that great which is hardly surprising given the miles, so I'm going to clean them up, paint them red and reapply the Porsche graphics whilst I'm at it.

Yes - Autodoc not only seems the best price, they are also in stock

(apologies if teaching your grandma about sucking eggs...but)

I hate to do this to you, but when you take them apart, do check how easily the old pads come out of the calipers, and more importantly how easily the new pads go in.

There is a stainless steel plate in each end/side of the caliper, which over time (due to bimetallic? corrosion) tends to lift away from the caliper base slightly, enough to prevent the pads from 'free' movement. If the pads don't move in/out as they should, they will be either wearing away too quickly, or not engaging correctly against the disc.

Hope yours are all good. One giveaway is if the old pads come out easily, and the new pads don't go in, the old pads may have been filed down to alleviate the issue.

[Orangecurry]

oooh no I'm not going to answer on that - the internet will have a better answer than I could come up with, and it depends what you have in there already.

Also - putting new pads in, you won't be adding brake fluid - you might even be syphoning some out

As you say (afterwards) do a full flush, especially from the clutch slave cylinder, so you could aim to expel most of the old fluid anyway.

And you didn't ask, but I use Motul RBF, as it is very very good, but doesn't cost stupid amounts. Is the latest RBF 660?

Time to start some DIY on my (mostly) self-serviced worthless old banger...

(yes there are two sets of front pads in the photo; don't worry I won't fit them all )

Rears exactly the same quality (obviously) as the fronts.
