DS 1.11 bedding in

[nickfrog]

Just fitted them at the front of the M2. Had to take the car out locally for a 10 mile errand but couldn't bed them in as per the procedure because of traffic.

I only used light braking and there was no squealing, they just felt like normal road pads.

First track day with them is 9th September.

So what do I do? Do I bed them in tonight when there is no traffic?

Or can I just carry on as normal and only bed them in just before the track day.

Cheers

Nick

Cheers guys. Sounds good. I will treat them as a road pad and then bed them in early on. The process is 25 applications at 50% while building up heat so perhaps on my way to the track the evening before as doing that on the sighting laps might be perceived as somewhat inconsiderate.
Good to hear they work well as they were £165 as opposed to near £300 for the usual RS29.
Will also put RBF600 just before the day.

Bedding in on sighting laps is not a good idea. You'll just piss people off following you and you may not be able to get enough heat into them. You also need to let them cool a bit between applications, so you 'll probably just run out of time and end up with them not bedded properly.

Indeed and that's why I thought it would be inconsiderate. Will do it either early that morning on the dual carriageway (traffic allowing) or the evening before.

For bedding in the DS 1.11 you only need 15 applications not 25.

Incorrect, as ever. The instructions that came with the pads say x25 to x30 at 50% of race pressure for 4 seconds (it's a race pad), building up heat progressively.

It’s on the Ferodo website, 15 applications is required.

Anyway it’s more about achieving a pad temperature threshold above 500 deg C, rather than an arbitrary number of applications which can be variable dependent on car and individual braking technique. That’s why brake temp sensors are mentioned. The brake application number isn’t the critical factor.

HTH

Not really as this is not my question.

You're really good at googling but I spoke to Ferodo last week as the instructions in the box are different to the site. They said stick to the instructions in the box, NOT the site. Instructions vary based on compound and suffix. I'll follow their advice.

Throttlebody said:

No worries, as you posed the original question and subsequent replies, it looked like you were a bit uncertain about how and when to bed in race pads, particularly when bedding in pad temperature is more critical than focusing on an exact number of brake applications.

No I didn't ask about the how but the when, I got great answers. I prefer to listen to the experts in fairness for the how. The way to get to the temp is as important as the temp according to them. If they say 25 to 30 for my particular pads then I don't really have any reasons to not believe them. I have been bedding in track focused pads for 20 years as I have found that religiously sticking to the manufacturers instructions works well for longevity and performance.

The DS1:11’s are thermally bedded from Ferodo so are fairly easy to bed in (basically burnishing up the disc) .

Cheers. Spoken to Ferodo again and some are indeed, with particular suffixes in the product code but not mine. They confirmed the process as per the instructions rather than their website which seems to be for the ones that are pre bedded in. Thanks for sharing your first hand experience though, that's much appreciated.

Nick have you a contact for these pads? and are you on the four pots fronts?

Yes I am on the basic blue 4 pots which offers a much better choice of pads. The Ferodo ref is FCP4611W. I bought them from Tegiwa with discount code Forum25. https://www.tegiwaimports.com/ferodo-fcp4611w.html

They were very easy to fit, you just need the right size punch for the 2 pins.

They rattle a little bit as they don't have the anti-rattle "ears" of the OE pads but you can only hear it at low speed and even then it's very muted.

No squeal so far but I haven't bedded them in yet, just normal road use.

I found that the DS1:11 didn’t make much noise at all on the street or even after track use. They created very little dust and worked well from cold also. I think you’ll like how they feel on track; very good release and modulation. Keep a check on wear after 1/2 pad life as mine went very quickly!

That's good to hear, thanks. I tend to bin pads quite quickly past the half point as too thin a pad seems to disproportionaly affect heat dissipation so it becomes quite easy to cook a thin pad, however resilient it inherently is (the M2 is heavy too) so it becomes a false economy. They're only very cheap at almost half the cost of RS29. I have Snet early September to test them but first impressions are very good indeed compared to the OE pad, it seems that I have zero dead travel but that might be due to the thicker pads as the fluid level has gone up a bit. Modulation is indeed very good so far but I need to recalibrate as the set up now feels a little over servoed, but I am sure it's simply down to the higher friction coefficient. I haven't put the RBF600 in yet but will do before Snet as this could be the next weak point (before the seals lol).

[nickfrog]

That doesn't sound like a lot of longevity but then again maybe you do a lot of laps per day.

I really like Snet, it's in my top 5. It's got a bit of everything and when possible I short shift the back straight and use it as a brake cooling section.

[nickfrog]

Those APs are beautiful and probably the best part of £3k per axle I guess? I am not sure my engine would cope with 1.4g what with oil starvation.

I’ve haven’t driven Snetterton yet (it’s a hike from North Yorkshire) but did visit the circuit last year to watch some racing...looks to be a great track; hard on brakes?

I would say medium. I could get 7/8 decent laps in the Meganes out of simple PFC Z which are road pads with a slight track bias.

2 big stops at Montreal and Agostini. They're quite close so if you've made it past Agostini then you're OK as the rest if flowy.

Brundle/Nelson can be a bit taxing too but they come after the long back straight and you can sort of "spread the work" between the two.

If you've never been, I would encourage you to try it despite the distance. I guess you're 3/4 hours away which is similar to me in Sussex.

I'll be there on 09/09 with Javelin.

Cheers. Cadwell is on my list of new tracks to try this year. Looks a bit daunting in places... Is it that bad / scary?

hi Nickfrog,

About to bed in my DS1.11 on the M2 and wondered if you had anything to share on your experience? Reading this I am off out this eve to find some fast quiet roads to do some hard(ish) stops. THen off to Donnington tomorrow eve.

They have proven to be the ideal pad for me on this car. They're not supposed to be as good as the RS29 which are 50% more expensive but in fairness they've been great so far. Have a great time at Donny.
