Upgraded rims and now screeching sound

Re: Upgraded rims and now screeching sound
I was previously on 20" Avangarde M355 rim (on F10 with stock brakes). After 3mths of screeching sound, I decided to change to 19" original BMW 351M rim and no more screeching sound after that.
I'm not sure whether it is because of 19" rim (smaller) or original BMW rims that help solve the screeching sound problem.
Anyone upgraded to original BMW 20" rim on F10 (non M5) with stock brakes? Do you get screeching sound while on light braking during cold start / low speed?

Re: Upgraded rims and now screeching sound
My previous ride had some sound but became really loud after getting 19" rims. Finally found the problem after 1 year after I printed out the caliper diagram from brembo and headed out to WS and ask them to disassemble. Found the back plate behind the brake pad was upside down .......after assembling it accordingly for the 4 calipers .... no more sound.

MW,
Is your previous 20" 356 style rim original BMW rim? If yes, this will more or less confirm that original BMW rims with stock brakes will not have the screeching sound.
I think with AG M355 rim + upgrade brake to BBK, will solve the screeching sound problem (this was confirmed by Ah Yang too)

F10 stock brake with 19" bmw style 366 rims...got screeching sound from rear when the brakes are cold. Disappears after 1-2 traffic lights.

Re: Upgraded rims and now screeching sound
I am also living with the same problem for about a year, got the 20" from Mr Y. screeching sound when brakes cold after warm up no problem. it is worst in the morning after my maid wash the rim last night. I had once when a pedestrian auntie walking on the opposite site of the road jump up a got a fright from the brakes sound... Now I am used to it.

Re: Upgraded rims and now screeching sound
IMHO - Don't think its brakes.
Likely rim lugs are not torqued to specs.
Please check that each lug is torqued to 120nm.........
Over-torqueing does affect the rotors giving an impression that the brakes are having problems.

Re: Upgraded rims and now screeching sound
had the screeching sound too after upgraded 17 to 19 rims... Sound especially loud before coming to complete stop. Should be brakes pads finishing.. End up I change a bigger brake kit cos got bro dekit. Problem gone.

Re: Upgraded rims and now screeching sound
Luck of the draw......if the mech just use an impact wrench and drill all the way shiok. Other mechs may be happy with just enough agr agar drilling. Either way you will never really know if it followed torque specs unless the right tools are used.
In both cases the wheels have to come off for the new wheels or bbk to be fitted. Some mechs may drill all the way.
I had BBKs and it still screeched all the way. I also changed to other rims and it still screeched.
Later I decided to follow specs and re-examine the schematics of the bbk.
Found that the backing plate for the pads was upside down and wheel lugs torqued to 150nm.
That mech had a religious belief that tightest is the best- which BMW is not aligned with.
BMW has a database of torque specs for nuts and bolts for a reason.
Look at your spark plugs and oil filter cap ..... The torque specs are etched there for a reason.
Same applies to the rims ........ There is a spec for the rims to follow.
Hope maybe that might throw some light into the mystery.

Re: Upgraded rims and now screeching sound
Sometimes mechanic will not using torque wrench due to save time and effort.
If i go repair or alignment and the mechanic was not usingtorque wrench to tight my rim, i will ask them take out and retight again with proper torque with proper torque setting, sounds like fussy owner but me and passengers life is much pricier than that extra 5-10 dollar labour charge.
