Please tell me the tap size for the thread in the hole of the caliper guide pin, front brakes on a 2000 Dodge Durango 2WD 5.2 eng. Or the matching thread from Mopar part 04886075AA. A prior brake job stripped one hole and I was not told, and a coil insert was used. Which was not exact enough, the inner pad on that wheel wore out way before the other front pads. Even though it had issues, this vehicle is approaching 200k miles, this maybe its last brake job so i’m trying the insert route again. But the pin is binding before its threaded in fully. So want to tap the hole after i insert the coil. But trying to ID the thread has been a problem. The Dodge dealer parts man said “they don’t have that info, try the service dept”, The Service Mgr (Assist?) claimed ignorance of the info i was requesting. One parts store counterman told me the thread on a brand new pin was damaged, another tried matching on the store thread guide and a thread repair kit, but was not sure. He suggested calling Dodge. I called, submitted the info request for tech dept, a few hours later got a call back, “We don’t keep info on vehicles 10 years old.” I have tried the taps i have on hand on the good hole, 8.0x1.25 went in loosely, 5/16 18 & 24 did not fit (i did not push it, did not want to ruin good threads.) Another parts man who owned a Durango and the same problem, suggested an self tapping oversized pin, but the previous mod to the hole may not permit that. Any other suggestions?
