Pagid RS4-2s pad build up / vibration

Rich, is the spacer part of the bell, or on top of it? I don't understand why two different metals would be butted up against each other in the first instance, they have conflicting properties when subjected to heat. If the latter, then it's ok.

To also note, as in the first post by the OP. J hooked, Slotted, Grooved or whatever pattern you like don't stop pads sh*tting themselves all over the disc and causing judder.

Without spacer


Better pic to show the spacer (ignore caliper... they were sh*te so came off)


As mentioned before... braking from 60-0, causes no vibration and the stop the car incredibly quickly. Its just when over 90-100 (which to be honest isnt very often)

Yea i have non floating 340mm tts ebc usr discs
Same calipers and pads as rich

I suspect rich drives his car harder than mine (hes a lunatic from the midlands)
Without sounding like a bellend know it all
 i fail to see how ive overheated pads designed for racing with 95% road use (my normal commute is 5jcts  on the motorway lol) and one trackday. Which was possing with rain anyway so not going flat out anyway :-)

They have never faded,  never sat on the brakes after stopping etc. I know about looking after brakes. Alex did all the bedding in and he was gone a good 10 minutes and my car was umm well used when it came back so i have every confidence in him bedding them in.
I may try running through the bedding in process again for what good it wont do.


I phoned alex when i was at the trackday and he was helpful saying it sounded like pad buildup/deposit also.

As i said in the other thread im going back to alex for some more modding and when I'm there as long as its ok with him,  i will whack on some new discs and pads and new fluid  (only just over a year old anyway). It is always in the back of my mind when I'm out for a drive so best remove that.

Cheers for input tony but while the rs42 is a good pad in terms of cost / performance across temp ranges and life (ive got like half the pad left still) i think they are are quite finicky and can (note i said can not are) be problematic for some cars / set up / conditions.
