Following a recent brake service that included pad replacement and rotor resurfacing, I have observed a slight delay in pedal response accompanied by a transient high-pitched noise during initial deceleration. The service adhered strictly to manufacturer specifications regarding parts and recommended bedding procedures. However, given these observations, I am evaluating whether the issues may be associated with rotor machining tolerances, slight misalignment during caliper reinstallation, or possibly a residual lubricant not fully removed during the service process.

Has anyone experienced a similar phenomenon following brake maintenance? In such cases, what diagnostic procedures would you recommend to confirm that the caliper slide pins, flexible brake lines, and master cylinder are not contributing factors? Additionally, are there specific tests or data logging methods you have used to isolate whether the noise is mechanical in nature or perhaps a transient high-frequency vibration related to pad bedding? Any insights or shared experiences regarding troubleshooting these post-service indicators would be valuable.

I had a similar experience after a brake service where the noise and pedal feel were off initially. What ended up helping was checking the caliper slide pins and confirming that the rotor run-out was well within spec using a dial indicator. In my case, a light re-greasing and double-checking the caliper alignment made a difference. You might also want to briefly re-inspect the bedding process and ensure all residual lubricants were removed. Sometimes a quick follow-up service can clear things up without much fuss.

I’ve seen similar symptoms before—a bit of a transient noise after bedding in can be normal until everything breaks in fully. Still, if you’re noticing a delay in pedal feel, I’d cross-check the caliper alignment one more time and verify that rotor run-out is truly within tolerance using a quality dial indicator. Also, it might be worth driving it under varied conditions to see if the noise profile changes, which could help pinpoint whether it’s a bedding issue or a slight misalignment.

Another aspect to consider is the initial break-in period. Sometimes minor noises and a slight delay in pedal response are part of the settling process until all components fully conform. If the issue persists beyond a few hundred miles, it might be beneficial to run a torque check on all mounting hardware while the calipers are hot, as thermal expansion can affect alignment subtly.
