PFC01 Pads Making Sparks?
I just installed a pair of stoptech st40 calipers and 355mm rotors on my E46 M3. And tonight I took it out to do a few 60-5 runs to bed the pads in.
Here's the thing, from the passenger side I saw sparks under heavy braking. Please note that the rotors have about 500 miles on them using the stoptech pads. So is this normal? |

Are the pads new? If so, that is totally normal. Alot of times there is sediment, or the edges are not chamfered which causes the sparks upon bed-in. Either way, I wouldn't worry about it.
I've done a bed-in before many times on track pads with non-chamfered edges and it's a spark show at 10pm at night Is it making a loud grinding noise, or does it sound normal? Chamfered: Non-chamfered (which is what you may have) |

Thanks for the info.
They aren't making any particular noise. Yes, the pads are brand new and I believe they aren't chamfered. So I suppose that's what's going on. It seemed a little weird that they weren't sparking from both sides, but everything seems normal otherwise - no pulling or anything. |
