My '00 Trooper's brake pedal has started making a creaking sound every time I apply the brakes, which is kinda annoying. I've stuck my head up under the dash to try and isolate where it's coming from but it's difficult to pinpoint. I've also sprayed (a lot of WD40) everything I can see that looks associated with the pedal assembly with no luck. I'm wondering if there's anything that could creak the other side of the firewall within the master cylinder area.
Anyone had a similar creak, and fixed it - please share
TIA
