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

The last few times I’ve had pads fitted I’ve driven approximately 20 miles homeand just used the brakes very lightly. I’ve then gone out late at night and bedded them in when the roads were empty. I’ve never had any issues doing that and that’s with a few different makes of pad too.

Not much help I know, but I hope it’s of some use.

Doesn't matter really when you bed them in properly if you're only doing light road driving between now and the track day.
If anything, some road driving will get the first stage of bedding done better than trying to do it all in one session.

As above I have used DS1.11 on 2 different cars several times that are road/track & just run through a quick bed in on the first session on track each time, never had an issue, epic pads.

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.

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.

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.

Agreed.

At best, you're not concentrating on the point of a sighting lap. At worst, you catch the guy behind you out.

The DS1:11’s are thermally bedded from Ferodo so are fairly easy to bed in (basically burnishing up the disc) I usually get some initial heat into the system then run 10 to 15 hard stops. They are very good pads for feel and release. I used RSL29’s prior which lasted longer and were good all the way down. I preferred the DS1:11 but they were not as good toward the end of their life.
I have the DS3:12 now but haven’t had the chance to try them on track yet.

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.

Yes, that’s right there’s a suffix that determines if they are thermally bedded! You are right in that the best info is from the manufacturer. Tim at Circuit Supplies (Ferodo importer) is a very good resource.
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!
