On Monday i did my first ever proper track day, at Anglesey, and had an absolute blast.

There were some serious machines there and a hell of a lot of Caterham/Lotus 7 type cars too, which meant combined with me being at a novice level in a car not really designed to be belting around a short track with standard brakes, i was going to be in the way a lot!

















There was an old God knows what there, looks Morgan ish



And also a MK2 Jag that i didn't get a pic of as it lost oil, blew its engine and popped off pretty early on in the day.

I managed to get some good pics from the on site photographer, i'll just pop 1 or 2 up







Overall, i think the old girl done well. I overtook a few cars that i really didn't think i would do, and also got passed by a few that didn't look up to much but were proper track weapons!

Running standard brakes though was a downfall. I could only stay out about 5 or 6 laps before having to cool down a bit. Early on in the day i suffered from what i now think was a cocked/stuck outer pad on the NSF caliper. This resulted in the paint blackening on that caliper and it took all the pad material off down to the metal whn the other side had about 5mm left. With the inner pad also being OK, the pad warning light never illuminated and so first warning was a bit of a nasty noise! You can see here a new pad compared to the inner thats worn normall, compared again to the one making all the row!





Being stuck late in the morning session with that i couldn't continue using the car. At lunchtime i ventured out to the local petrol station to fill up and ask about getting some pads. Turns out 1 junction down on the dual carriage way was a CES parts shop and they had a set in stock. I suppose thats the good thing about BMW putting 530i pads on the front of the M5. They're ****e, but they are stocked everytwhere!

So £40 lighter i limped back to the track. Without a tool to my name i borrowed a jack, socket set, pliers, screwdriver and G clamp off various people there better equipped than i and changed the offending side only, simply as i wanted to get back out as quickly as possible, and also as my BBK will be on in the next week or 2 it seemed pointless doing more work for nothing.

An absolute credit to the type of people you see and meet here. Lending tools out and generally helping out anyone in need i wasoverjoyed that there are still decent people out there, it really made my day

With new pads in i completed the rest of the day with minimal drama. I had to come in to cool down but much less so than in the morning. There really must have been something just stopping the pad from releasing.

The blot on the day was however, some debris from either trackside or possibly from my brake episode has nicked one of the spokes on my alloy, meaning i'll have to address that with a refurb. I've called up the Wheel Specialist where i had mine done and they are confident they can match it, although i appreciate they can't stone wall guarantee it due to the nature of how these are painted. What i'll likely do is get the 2 alloys on that side done, that way if there was any slight discrepancy, you wouldn't notice as both wheels on each side would be the same as each other and wouldn't be seen together.

You can see here the drivers side caliper looking normal, compared to the passenger side which took the heat, and the chip to the wheel.









Likelihood is i would hunt a set of generic 18's down and fit them with track rubber should i want to do this again. And i do!!!

Excuse the exposed wheel nuts and lack of dust cap, these are like this due to checking of pressures on the day and changing the pads over, its not normally like that!

Hey Jamie,

Great to see your M5 being used on the track!

Which BBK are you getting? When I upgraded mine it was a huge difference for me in feel and confidence. Certainly a must upgrade if you intend to push yourself and the M5 higher limits.

Car is looking proper out there! Its quite a treat honing a 2 ton sedan (or is it saloon) on track like its nobody's business. The E39 M5 is a gift that keeps on giving.

LOL +1. I'll add to that in the sense that I grew up in the UK, moved to Texas 21 years ago. Jamie & the other few Brit's that post help me stay in touch with my roots in a roundabout fashion. (Terms like "NSF" Near side front, I remember my dad using such terms LOL)

My first day on a track in the M5 was probably the best thing I'd done in a decade. Glad you got out there Jamie.

Yeah good to see he's actually cornering the beast LOL. I was pretty much evenly matched with a guy in an E90 M3 on my first day on the track, it was his first track day too.

One of the things that first amazed me about the E39 M5 and BMW was how they could make a big heavy car feel so nimble & chuckable. My E60 550i sport was just as nimble.

if your caliper got that toasted perhaps you should consider a brake line on that corner with fresh fluid.
That's a good point Topaz, new braided flex hoses on all 4 corners with the BBK may be a good idea.

Maybe you can find a spare set of style 65's or M-pars that are not in perfect condition but get a decent price on them and use them as track wheels.

Maybe the added cornering force caused some extra "knock back" on the offending pad and caused it to get cock eyed, therefore wedging it? This maybe especially so if you have a wheel bearing starting to show some wear, the hard cornering caused the wheel & disc to push the pad back, then get wedged?

You'd be surprised the decent condition of the rest of the brake on that corner. I was expecting the whole caliper to be showing signs but in actual fact the outer paint blackening is the only visual. Also given the calipers are painted it makes it look so much worsed than if you were running standard unpainted ones.

I'm not saying something wasn't right, of course it wasn't but i think as touched on here the pad has cocked and jammed somehow causing tha outer pad to deteriorate. Even the dust boot on the caliper piston was in great shape when i removed the caliper to swap pads out. Its more of a testament to how much abuse these things can take more than anything. Sure, big heavy cast single piston brakes are always going to be under the cosh slowing a 2 ton car down repeatedly, but after a i changed pads i simply went out and did it all again, the car taking it much better.

If that pad hadn't wedged on, i would still have had to cool the car after lapping for a while but nothing like what i was experiencing early on, my afternoon session was a total hoot without real hiccup

I have new lines to go with the BBK that are provided (standard lines are not compatible with the BBK calipers) and new braided lines for the rear with new calipers too. As said fluid will be upgraded throughout so i'm more pissed at the wheel chip than the black calipers at the moment.

The plan is to at some point get some cheap 65's or m paras and use them on track again as mentioned above by mordor.

Thanks for the comments guys

Jamie

Anglesey is a brake heavy track. Every credit for unleashing the M5 there. Were you using standard pads to begin with?

I'm using Carbotech XP8 pads all round for road use. They bite really well with some heat into them. The downside is that they squeal like a pig and the dust is killing my wheels. I think I'm going to try the new Pagid S pads....they seem like a decent uprated user friendly road pad. I'd love a proper big brake kit.

Enjoy!

Yep, standard discs and pads all day, even after the changeover, hence the "issues" I (fully expected to) experienced.

I've been looking into the best pads for my BBK setup and by best I mean whats best for me regarding the most use my M5 sees as opposed t best outright braking performance.

I looked at the carbotec but decided against them simply as heavy dust and squealing is a big no no considering pretty much all of my driving will be normal road based.

At the moment i'm looking at a more wallet friendly yellowstuff or similar

Would be a shame to get cheap pads on an expensive brake kit. Yellowstuff get very mixed reviews which put me off. The Pagid RS19 has been recommended to me as a pad that is designed for endurance racing which is user friendly and kind to discs (lower dust levels due to lower disc abrasion). Not cheap but Pagid are the best in the business.

I use Pagid rs14 in my lotus. On track they're eye watering, fantastic stopping power. They're very useable on the road too. Obviously it's a much lighter car with better brakes as standard but the Pagid pads are very very good.

They now do a road biased Pagid "s" pad with is E marked for road use. Half way house between full track pad and road pad. Should be good enough for my road use in the M5. I think I'll give them a whirl.

I really didn't think choosing pads would be so difficult for road use but its a head scratcher.

I've been given redstuff with the kit and was initially going to use them, purely as they're pretty good to discs and offer low dust output, combined with decent stopping power.

However, they too receive mixed reviews and i was pushed towards yellows. They seem a better pad in terms of performance, but i've heard they are dusty, which put me off. Cleaning style 65's every 2 days isn't my idea of fun!

Carbone Lorraine was my next suggestion but again i've been told they are a dusty pad, Xp8 or 10's.

Whilst i appreciate that a dusty pad is likely one thats a good performer and kinder to discs i don't want something thats going to cake the car in dust when i won't be using that stopping power most of the time.

Flip side is i don't want to short sell the kit as you've pointed out putting poor pads on.

If i had to choose a pad and compromise one characteristic it would strangely be disc wear. I'd happily have discs lasting 20K as opposed to 30K if the pad bit well and produced less dust than normal. I value my time more than £400 every 3 years as opposed to 4 years rather than cleaning wheels twice a week for an hour a time

The final head mess is that simply looking at the EBC site comparing red to yellows shows the cost difference as negligible so its like the pads are designed to have different characteristics as opposed one made better with better materials????

I may look at the Pagids too, but my little knowledge on the subject makes me look past pads billed as endurance pads simply as i think i'm not going to be using them in that manner, i may well have a rethink

Pagid RS29 is an excellent pad, id happily recommend these as totally useful on the road and track. Not personally a fan of the EBC product.

Didnt know that about the front brake pads! Good info.

The damage comes with the territory on track. Many nicer cars use painters (blue) tape here in the states and cover the entire car or front of car to prevent paint chips. Someone drops a wheel or two off the pavement and you have rocks flying up at you.
Thats the main reason I ended up not running my M5 on track and instead bought an older Miata as a track car.

Great to see an M5 out on track though! Looks like you got the full experience (with the helpful people in the pits) and had a good time. That's what its all about.

I just bought a set of Pagid RS29s for the front of my M5. I don't track it much but having gone through various different pads on the other cars I found RS29s to be the best and am now in the process of fitting them across the fleet as the current pads wear out. To me it is worth the expense to get something that can take any abuse rather than fitting a different type and finding out that they disintegrate after a few track days. The only downsides that spring to mind are the high cost and the fact that they made them to order as didn't have stock at the time so took about 6 weeks to arrive.
