once the brakes heat up a bit (after the first 10 brake applications from cold let's say) yeah, the noise is high pitched and continuous at moderate to low pedal pressure, when stamping on the brakes hard it goes away most of the times but I can't brake like a hooligan all the time lol. And it...
mhhh not much at all, maybe 100, but I did bed them in properly. I know I was thinking the same- just let them settle even more but trust me- the noise is unbearable :(
I booked the car at a garrage on thursday to be checked, maybe extra brains will do something. Didn't swap the adaptors because it was late an I had no time left last night, but will surely be doing it on thursday, I'm kinda pissed off because I planned to do it yesterday but as said time only...
Back again.
Took out the caliper, Inspected and cleaned all contact points, re checked the pads for free play, wheel bearing seems ok (no play). Put it all back together nice and tight an it still squeaks.
I swear to God I have this car for 18 years, went through engine and gearbox rebuilds...
To sum it up:
1. Get rid of the squeal
2. If these brackets last me this season I'm happy.
I'm gonna switch to 300mm discs next year and probably the pms dedicated brackets.
They work with the 280 discs without having to drill the calipers like with the PMS kit. I don't know other brackets that can be used without modding the calipers. If you do then let me know. I'll Switch them and see
I've thought about that but if the nut that holds the caliper to the adapter is tight and then the adapter is tight to the hub there should be literally no flex as the adapter itself is a long bolt that goes through the caliper and then the bolt that secures it to the hub is close to the mating...
And yes the pads move freely, I had the experience with ds2500 pads on the old std calipers and I obviously made sure there’s some free movement there :)
Not so sure it's the caliper but it kinda points there. I used a torque wrench to tighten all down. As far as I last checked the wheel bearing is ok and tight. But will do a re check, thx!
I just came from doing a proper bed in session. Nice blue ish material deposit on both discs, I also had an infrared thermometer and measured temperatures both sides - gradually went up in braking force and ended up to about 200°C on both sides (measured the discs), max difference left to right...
Oh wait, you are talking about chamfering the pad material right? Well the Valeo pads were chamfered from factory and it still squealed like a stabbed pig so it's not that
That I think was applied to the std calipers when mounting ds2500 pads that were a very tight fit. On these 197 calipers the pads move freely, so I don't think that's the issue
Only thing that makes sense is there's still a difference in how the pistons slide in and out, thus pressing on a certain pad unequal and creating the squeal. Meaning that if one of the two pistons of a certain pad don't push by the same amount it creates that sound. Maybe there's some tiny air...
This is a 2 minute read so bear with me pls!
I recently got said calipers from a guy, got them powdercoated, brand new pistons and seals, new pad hardware (pins and anti rattle shims), DS2500 pads and new Brembo max 280mm discs.
This is my second attempt to to this job, first time I cheaped out...
different camber adjustment between left and right photo. I guess the advantage is that the wheel runs a bit further away from the BC strut, but if you run spacers that doesn't matter actually as there's no chance of rubbing
Hi,
Having upgraded my 182 to said calipers, now I'm after the DS2500 pads to fit them and wanted to know if them pads require some filing like the DS2500's for the std caliper did?
Sorry if that has been covered but I couldn't find a thread on it (I guess they don't need to?)
Thanks!
I just refreshed a pair of 197 calipers and fitted them to my 182, but the front right one gets hot, I also put brand new brembo max discs but OE Valeo pads (they came with the calipers as a bonus from the seller) and after some harder braking action the right disc got brownish in colour and the...
