Technical What will you do where your brakes wear out ?

I think the standard brakes on the 1.4 are a bit pants. I've done a lot of experimenting with different pads and fluids etc. I posted this on another forum but I'll copy here to avoid re-writing it:

Regarding EBC:

Greenstuffs are fine for the road if you're not too heavy on the brakes. I had a set put in fresh for a Nurburgring trip last year and honestly, by the time we got to Eddy's I was calling the Fiat dealer to see if they could hook me up with a standard Fiat set. Dreadful performance pad. Bits chunking off them, glossy glass melted look to them after a few good stops. They stink horribly as they deteriorate too. Like melting plastic smell.

Yellowstuffs are brilliant. I use them on the race car and I'm having my EBC contact make me some 500 spec yellowstuffs in the lab. They're incredible. They stop you in much shorter distances, they don't fade, they don't chatter or squeal or take ages to warm up. A good 30% harder on discs though, you don't get nothing for nothing in this world.

Regarding others:

Fiat original part pads......are made of cardboard and bits of dry clay. Fade-tastic and short lived. Give it a miss unless you're really stuck.

Ferodo normal road spec pads (1500) are surprisingly good. Good enough to stand up to the punishment I doled out at the Spa and 'Ring trip and keep going for another 3000 miles before they cried enough. For pads that cost me £20 at the local motor factors that's not bad going.

Ferodo 2500's aren't bad. People rave about them but honestly, they're not all that. I actually feel the yellowstuffs are a better bet. The 2500's were grabby and gave the braking an on/off feel. They also didn't last very long. The Ferodo 3000's I haven't tried yet, but like the EBC Blue's they're track only. Have to be up to temp and are utterly, scarily useless in the cold. I watched a BMW guy stomp the pedal and sail past the corner while his 3000's were still cold. To say nothing of them being technically illegal for road use.

Red Dot fast road/track. I recall these as being pretty good. I last had a set fitted 2 years ago. They didn't last a huge amount of time as I recall but the bite was good. Fade was more noticeable but at the time I had standard brake fluid in so draw your own conclusions there.

Pagid Black. I've just fitted a set of these on all four corners of the 500. Still at the bedding in stage. I had to replace the rear bearings and the discs and these pads were what was available in a pinch. I can report back later when they've bedded in and I've taken Isabella for a decent thrash in them. Update: They're not bad. Not great, but not bad. The pedal actually feels more elastic under braking and the ABS seems to kick in later. Odd.

Worth noting that in all cases my front discs have been EBC Turbo Groove and generic pattern discs on the back. The only exception is the yellowstuff. My experience with them is on the race car which runs generic pattern part discs all around (ebc standard pattern discs in this case because they're almost free for me in return for stickers on the car). I'll report back on the yellows on the 500 when they get here next month.

The fluid has been a little varied throughout my experiences with different pads. Initially the fluid was Fiat standard stuff which boils if you look at it funny. I've tried generic dot 5.1, Motul Branded 5.1 fluid and what I'm currently running Castrol SRF.

If you're serious about stopping and you're heavy on brakes go for the Castrol SRF. It's not cheap at nearly £50 a litre but it works. Incredibly well. Boiling points are off the scale. Dry is 590, wet is 518. If you go with this then buy enough to fully flush your system out and don't do it by the push pedal, one corner at a time method. Take it somewhere, get them to open all four and get it pumped through with pressure. Then when you've put the standard amount of fluid in, pump another half litre through to make sure all the old stuff is out. SRF is patented chemistry and the formulation is different. It will not co-exist with other fluids happily. Interestingly though, it is safe for ABS equipped cars if my ABS is anything to go by.

Of course this is all highly subjective feedback but I'm heavy on brakes, I change them a lot (to the point where I can do front discs and pads change in under 20 mins) and I try to think about the differences in characteristics. Sometimes you're surprised (cheapo ferodos!) and sometimes you're underwhelmed (greenstuffs).
 
Good performance advice there Jason. I'll be interested to see how my standard Brembo stuff compares.

I've not got anything against the standard Fiat stuff tbh, although it is a little on/off and makes progressive braking difficult especially for the wife who is used to burying her foot in the floor to bring the Subaru to a stop.

A guy I worked with had a rennosport Clio and was running Pagid yellows and whilst I can't say how they felt when cold, their stopping power had my legs rising up into the air...... Pretty sure he was running Castrol SRF on that car.
 
When I first come on the FF it was recommended that I upgrade to a Ferodo 2500 pads and in hindsight it was a great recommendation. But since I don’t believe ‘what I read on the internet’ I did some ‘searching’ and boy was I in for a shock. Brembo got mentioned earlier on but their pads are made by Mintex who have an excellent reputation. They also have their own brand namely 1144 (fast road) & 1155 (race pad). I don’t know who makes Fiat’s OEM pads.

I was striving to reduce the brake times on the 500 similar to the A500 reducing the stop time of 60-0 from 3.2secs to 2.6secs. I reckon this was down to tyres (Maxi raised this) and possibly the bigger discs on the A500.

On the benefits of better pads e.g. EBC Greens have reduced brake dust. Grooved discs will stop the build up of glaze. This has been a ‘bug bear’ of mine on the 1.4 with the rears. So if you change you might as well have the dimples in place of the better looking but suspect cross drilling (holes) and of course the fronts are done as well.

There is a temptation for individuals to skip the brake fluid change at 2 years. Here’s a reality check on this cost saving (acknowledgment to Ffoxy)
Brake fade could be due to brake fluid being past its best, it should be changed every couple of years as it absorbs moisture which causes the fluid to boil up at a lower temperature with heavy use, causing an air lock as steam compresses very easily allowing the pads / pistons to lose pressure on the disc.

There's also another ‘school of thought’ - put on really good gripping pads and ‘to hell’ with wearing out the discs. The standard ones are cheap so does it really matter if they wear out 30% quicker ? This is US test comparing pads and after the first brake demonstrates that the Yellows perform better than all the pads after 4 brakes. The other contender that gave the best 2nd brake was one that I’ve never heard of – Hawk HPS but it got criticised elsewhere. I came to the conclusion that the weight of the car is a factor is the optimum pad and the Yellows suit the 500.

I emailed an ebayer Motor factor supplier last Friday asking him if the Ferodo 2500 were road legal and this was his response…
Not in the uk on a car made after 2000. they have too much friction and fail the test as a result - check your local laws.

So that along with the Yellow pads can present a deliema for some.

Orange = Mazda
Green = Hawk HPS
Light Blue = EBC Yellowstuff
Dark Blue = Hawk HP Plus

As a FYI (For your information) Mintex don't do a performance pad for the 500 1.4 or A500 - this were supposedly great value for money at half the price of the Ferodo 2500. TMD Friction UK replied to my query but have given the part no. if someone was looking for the standard pad which is probably the same one that Brembo supply...

Hello Michael,
Pad details as follows
Fiat 500 1.4 07> MDB2239
Fiat 500 1.4 Abarth 08> MDB2240
Unfortunately we do not do uprated versions of these pads.
Kind regards
Lee
 
See that graph is interesting, but when you consider the fact that the vertical axis doesn't start at 0 then you realise that the distances are small. Keeping your distance and having a good set of tyres on will make more difference than better pads :)

Difference in braking by better pads is only showing between 10-20 feet and that is at 100mph ! so you are correct. The only benefits is less dust and less fade and hopefully no squealing like some have got with the ‘fast fit’ ones !

Re the tyres the URL posting with Autoexpress shows a difference of 8M ! if using Continentals over a different brand at 50mph in the wet. In the dry there were differences of 4M at 60mph with all season tyres doing poorly (this are a standard fit on US 500s). So there might be an argument against Eco tyres and a benefit in having an over tyre’d 1.2. ;)

It’s hard to justify the price of the more expensive £100 pads but TMC have a site offering alternatives. If you heart is still set on a set of Ferodo 2500 ebay have them for £105.

Here is a good summary of the different discs. The only discs that work ‘properly’ with holes in them is where they have been cast in them like the ones on the Porsche, Ferrari, Lambos, Maseratis, etc. On the Group N discs they are solid because of regulations. So it looks like the Grooved ones (good for de-glazing) with possibly dimples (for show) is the way to go IF you were looking to upgrade.

All seasons are standard in the US because they really do need them. IMHO if you don't want to run 2 sets of tyres you really should be buying all season tyres, they'll pay you back double in the winter.

Personally I stick to my cheapy brembo pads and discs. For the Subaru I might get something better if I can't fit 4 pots under the standard wheels.
