In one of the caliper pin lube threads it was mentioned that Toyotas caliper lubricant doesn’t hold up well over time.
I decided to check the pins on my 21 ch-r with only 26k miles on it and three out of the four pins were stuck on the front calipers! I didn’t do the rears yet. One was really stuck and I had to use my wrench to turn it back and forth to loosen it up.
Two things were strange to me:
1. The stuck pins were hard to rotate and didn’t move out. But they sort of let go and then, they moved freely.
2. The lubricant that Toyota used hasn’t hardened up and there was a normal amount of it. There was no rust or water intrusion.
I’m quite perplexed as to why these pins would get stuck like that. Does anyone else experience something similar?
I’ve never had something like this happen where there was sufficient lubricant, no water intrusion or rust, yet the pins were stuck. Is this Toyota specific issue and perhaps related to their glycol based lubricant?
