I recently had new discs and pads all round and got told the obligitatory phrase '..brakes need bedding in..' from my mechanic but never actually knew exactly what it meant. My understanding was just take it easy for a 200 odd miles and that was that. But after doing some research it seems you need to do this 60mph to 10mph, straight back to 60mph down to 10mph and repeat FIVE times...
So basically i've never ever done that proceedure in 8 years of driving!! Have any of you done this and will it be a noticable difference in performance afterwards?
NB: All standard parts btw, not performance stuff.

If you've had new discs and pads, it shouldnt take much bedding in, just drive normal. The only case where bedding in is needed is if new pads have been fitted to a old disc, as the pads have to wear to the contour of the disc before full contact is made with the pad. I wouldnt do the 60 to 10 mph thing ether way, youll end up over heating the brakes and possibly warp the discs.
-
Yeh i see what you mean but i've read at least 3 articles explaining that the 60mph to 10mph is the best way to get the pad to transfer properly to the disc. Apparently its only if you stop to a halt you're at risk of warping them.
Never heard of anyone doing that method until now tho so really after anyones experience whos done it themselves if possible :)

Just don't thrash the hell out of the brakes for a couple of hundred miles and you'll be fine.
The pads need to 'bed in' to the discs and key up which is what the bedding in is doing, as well as tempering the material in the pads.
In eight years, you've changed discs and pads before right?
The car stopped afterwards, right?
What are you worrying about?

This,
Basically you're waiting for the surface of the pads to adapt to the surface shape of the discs.
Stopping distances will be longer to start with, but will shorten as the pads start to "Bed in" to the discs.
Realistically, an hours driving will sort the brakes out, and re adjust the driver to the new stopping distances.
Other than that, just drive it, the rest is BS :smiley:

Russ don't bed the brakes whilst they are out of the car okay :laugh:
Sorry mate can't resist!
You over analyze a lot of things and I can sympathize :wink:
-
Don't forget to make sure you bed them in when reversing too. For this, go to a carpark late at night and reverse around for an hour or so, from 30mph to 10mph.

I thought j turns were the only true way to bed your brakes
-
How much consideration do people with brand new cars give to this I wonder?

There's 3 articles explaining the 60mph thing, the reason why I ask as ive already said, is there must be a benefit in doing this otherwise why would the top 3 google hits be about this? I just wana get the most out of my brakes.
-
What came first tinternet or the wheel? :laugh:
Listen mate ever since I was in nappies and driving, my old man used to say......!
"Drive 100 miles normally keeping your distance from cars upfront"
"After that the brakes are bed in" :wink:
Simples!
-
haha ye ye but they used to think smoking was good for you so that old saying thing doesn't mean anything to me :P
-
The rules I follow (not saying it's correct) is take it relatively easy the first couple of hundred miles and leave the car in gear if parking on an incline during this period.
-
So literally no one has done the 60mph thing..?
-
Ignore the ebc one as they come coated with a bedding in compound/coating on the pads and need bedding in different. I have asked my suppliers brembo and ferodo and have not got a definite answer on best way so I advise to drive normal and be aware stopping distances may be greater until bedded on which is around 200 miles
