Caliper Pin Bushing

[Patrick0525]

I have a Toyota Venza V6 and I am planning to do the front/rear disc brakes and re-lube the caliper pin.
There is only one bushing.on the lower caliper pin.
Where does it go in relationship to the caliper pin? Sorry for the newbie question.

Do you mean does the slide pin with the bushing go in the higher or lower position ? If you look at the pin itself, there's an obvious groove where the bushing goes.

Thanks. I have not taken apart a caliper pin assembly in years. From my readings, I believe it goes in the lower position.

See where the notch is at the end of the pin, that's where the bushing slides on to.

At one point, what I was seeing was that the pin with the bushing typically went in the "leading edge" pin position. Even that's not consistent though.

Have the brakes been done before on this vehicle ? At 80k miles, I presume so. If not, you should be able to go by where the factory installed them so pay attention when you take them out. Otherwise, see if you can find a field service manual for your specific model. I have the FSM for my '08 G35 and it has different brake options and I'd have to double-check but even on the same model it's not consistent. On the 1-piston caliper it goes in the top and on the 2-piston caliper it goes in the bottom or vis-versa !

Do not use anything but silicone grease on the slide pins. Several of the goopy Permatex brake grease products will swell the pin and make it very hard to remove next time you service calipers. 3M silicone brake grease is the gold standard for this application.

Thank you for the excellent photo.

Ever since I found out that Syl Glyde is mostly castor oil and only like 5% silicone I've wanted to get some so badly, but the price of admission is a little high.

I was miffed when I spent $20 on a small bottle of Permatex copper anti sieze and it was only half full.

This is widely used. Do not use anti seize here.

No, these are the original front/rear brake pads @85K highway driving. PA annual state inspection on March 2 says the rears have 5/32 and the fronts have 6/32. Need
to do a summer time brake job.

Plan to use NAPA Sil-Glyde on the pins and PasteLub on the rest.

My company colleague has been using white lithium grease on his caliper pins and swears by it. He says no swelling or brake issues ever.

+1 This is 100% correct. It must be silicone anywhere there is rubber.



NOW, if you wanna go all out get a tube of Toyota Rubber Grease #1206. It's reddish pinkish. It is for the pistons, boots and slider pins.

Toyota has their own Caliper Grease (white) #80609 for the clips, edge of pads, and solid plates. In other words, areas where metal will rub.

Toyota uses Molykote As-880N Grease on for the back of pads where the shims ride. This is the black grease you get with Toyota shim kits.

I spent days gathering this info. You probably won't feel like messing with it but it is good info.

In this case, just remember which position the pin with the bushing is in. As I mentioned, the rear brakes might be the opposite too.
