Pagid RS4-2s pad build up / vibration

[rich83]

Pads recommend and bedsed in by Alex. No brake cooling. No brake stone guards.

Spent 2k on this kit and the pads are the weakness. At some point I've cooked them and breaking from 100 mph is horrid. Need to sand the discs.

[tony_danza]

£2k. Ok. You're committed to these then.

I can't say how well bedded they were, how could I? But it sounds like they weren't sufficiently done or they're running massively hotter than the pads can cope with.

Need some temp stickers/paint ideally.

I've always used project mu pads after an awful experience with pagid. I don't like the pads at all! You definitely get what you pay for in pads!

[tony_danza]

I've used them with no problems, but then I bought the right pad - I don't mean that in a smug way, but it seems it's easy to fall foul with them.

I run Endless in my current car. Favourite by far.

[rich83]

I'm thinking project mu or endless, is the only option. Can i run then on my current discs?

It's ridiculous. I bought this kit because I knew (thought) that they would deal with anything I threw at them, and some. Bit disappointed in the pads. The brakes stop on a 6pence so they do work very effectively. Mike is right I suspect, wrong pad choice.

Potentially you could run the same discs. I would take them off to make sure that they are not buckled and caked in resin. As you over heated your pads they may have warped the disc and then they have pretty much had it...

[rich83]

They wont have warped... 2 piece discs. Jay is on single piece discs, so as we have the exact same issue I'm 10000000% sure it defo the pads/pad deposit.

If anyone is thinking of trying a different brand I can recommend Carbotech over Pagid.
I know we're talking about a different pad compared to the Pagids I had but moving to a Carbotech equivalent has solved my issues. They appear to be a very good quality pad.
Jim at JKM recommended them to me based on his and some other customer feedback. They ordered and fitted mine. Although mine were made to order they arrived in under 2 weeks.

You using the xp10 pad?

I am, yes. I could have also chosen XP8 but 10's suit the vehicle weight better.

Nice one, I'll give these a go, XP10 are just under £200 for the TTRS caliper.


Any of the lads with the problem pagids , I'll be happy to give these ago on my car on track to see if they cause the same problem .

[rich83]

What pads have you been running johnsy?

What pads have you been running johnsy?

Short answer:- £50 pagids from ECP.

i was after trying them first before I try a dedicated track pad, it would be nice to have an opinion on different pads/brands and thought the £50 pagids would be good for daily duties and a base line to compare any others against . Iv only had the brakes on the car since October so they've not been used in anger as yet

[tony_danza]

ECP Pagids are made in China under license. I'd throw those in the bin.

I ran XP8s. Excellent pads. Don't bed them on used discs, the compound reacts and it's horrible. At the very least, clean them with a garnet paper flapper on a drill.

[rich83]

Would the same go for any other pads too mike? Endless/Pmu?

Just to clarify the setup here...



Ignore the lack of pad contact towards the middle of the rotor, that was because of the other F40 calipers (which didnt work) and pad size being wrong.

[tony_danza]

I'm confused by the bell. Why is it alloy in the middle? Are they fully floating bobbins, or just fixings, can you see 'tell tale' movement marks to show if they're dealing with the expansion correctly? If they were set to different torques, for example, they may not be dealing with the heat very well and jittering.

Nah, I put Endless straight in after the OE BMW pads and didn't have a problem. Likewise with the RS29s on the one before.

I would pick the Endless ones, mostly due to the fact mine have done 22k & 7 trackdays and they've only gone from 16mm to 11mm. They may cost more, but by God, do they last!!

I used to do a set of XP8s in every 2-3 trackdays. 

[rich83]

That alloy piece is a 8mm spacer to clear wheels. They are fully floating I think, will check for expansion....

Ive had them quite hot only once or twice.

I think im gonna go endless. Where did you buy yours from?

[tony_danza]

Sounds fairly normal. Surprised they're that hot on the road.
