Resurfacing brake discs ?

[Spark plug]

I think re-lining shoes is still fairly common in the truck world, but that again will be dieing out as more and more trucks and trailers move to discs.

the old rover 600 is hubs off to change front discs normally the comment is how much you must be kidding
lots of cars the rear disc is part of the hub anyway

Yup. Hubs off on my Mazda and not managed to disassemble one yet without knackering the wheel bearings.

Some of these designers have a lot to answer for, especially the one that makes you remove something like an exhaust to get to the oil filter.

Ordered a pair of discs from the link shown and am delighted at £31.39 incl P&P.

Disco1 (and others the same) need the hub stripping to change the discs, loads of cars have the rear wheel bearings pressed into the drum/disc too.

But really, how often do discs or even pads need replacing under normal (or even trackday) use?

Even at 80 quid a pair (plus time) compare the cost over say 100,000 miles to oil changes - I'll bet a brake rebuild works out far cheaper and quicker

But the trouble is some Discs wear as fast as the pads these days, even with OEM pads fitted

There's a ad on local radio round these parts recently, I may be kwikfit saying you should change your pads regularly in order to make your disc's last longer

Take a brand new car, with zero miles, to KwikFit and you will be told it needs tyres, exhaust, clutch, brakes and shocks

Grrr.

Just had my order cancelled

" I am sorry to tell you that there is an issue with your order.

We are currently out of stock of the disc brakes that you have ordered, I have then got in touch
with Brembo UK and they have told me that these disc brakes are now discontinued and are
no longer manufactured by Brembo.

I have checked with all of our brakes suppliers and none of the other companies stock the goods, therefore
I have no option other than to provide you with a full refund. I am very sorry for any inconvenience that we may
have caused. "

So that explains why remaining stocks as so expensive !

Clean up with electrolysis?

That's a bummer

These might do

Wheeler Dealers did do the "on car skim" of a set of discs on a Porch if I recall. Interesting to see it in operation.

Bit cheaper than eBay but still £60.
There is a "Plan B" but need to explore that at a later date

Lotus then decided to have a proper laff with the Eclat and Elite which have inboard DRUMS so you can't even change the bloody pads without a rear-end strip! Rumour has it that the diff and drums were taken from a milk float...

yeah Colin did like a laugh!!

But the trouble is some Discs wear as fast as the pads these days, even with OEM pads fitted

Faster in fact in some circumstances we had a tranny in the other day and the discs that where fitted month ago have worn 3mm already.

Discs are a pain to machine on a lathe coz the high spot usually becomes the low spot because the extra load from machining the high spot pulls the tool deeper at that point, every thing has to be solid and perfect and a perfect lathe to even attempt it, we used to have one resurfacer , that machined both sides at the same time but if done by the wrong person wrecked them.
I have used a flap wheel in the lathe with a vacuum cleaner! in preference to using a lathe tool when dealing with very expensive discs there was the old sd1 vented discs where £100 each and used to warp after couple of mths but once warped would stay in it that shape, so machining them was a requirement to a hard used sd1, as said I used to flap wheel the high spots and it worked a dream. I then put in sacrificial pads, at one point I did try sheets of emery cut to shape of pad

At one time you used to be able to get abrasive pads The idea was put them in to clean up a disc for a few hundred miles and then revert back to normal pads.

saw that the reason for the skim was set of discs and pads was quoted at £680 for the porsche

EBC Ultimax pads have a special surface so that is supposed to help them bed in quickly. Would that be similar to the abrasive pads that have been mentioned? Might be appropriate for lightweight cars where the rear disk brakes do hardly any work, and tend to acquire a coating of rust. Or is it just as effective to drive half a mile each week with the handbrake on?
