Toyota- Question about caliper slide pin bushing.

[Twisted1]

I had a question (and thought) in regards to the caliper slide pin bushings found on my 2000 Camry. I last replaced the brake pads and rotors in April of 2024, but had to check them out today after taking a 4 hour round trip, which contained a semi-hilly drive throughout the commute.

When I was roughly about 30 mins away from home, I noticed a “wub wub wub” noise from the passenger rear wheel when braking from 20-30 mph, to a complete stop. When I would accelerate, you could hear that sound for only a couple of seconds until is dissipated once the pads backed off of the rotor.

Today I pulled the rear brakes apart and visually inspected everything. I even placed my dial indicator on the rotor and wheel bearing/hub and everything was under .0004. I did find that the slide pins and the bores they sit in, basically dry. When I previously changed the brakes, I used Sil-Glyde, but since then had purchased Toyota Pink Rubber Grease. I bought brand new Toyota caliper pin bushings as well, which surprisingly did not go into the bore easily without force. The slide pin did not move freely, so I pulled them off completely. I don’t hear any clicking or anything of that nature, so I’m good with it. Also, the “wub wub wub” noise when coming to a stop has been alleviated.

Now my question; could I use two of the same bolts on the caliper that don’t have the bushing? My understanding from Toyota is that the bushing is there to help with a “clicking” noise.

Attached is the picture of the two caliper slide pins mentioned. Can I use two of the same (red arrow)?

After you found them dry, did you clean out the side of the bore with something? I use bore brushes for firearms, on a drill. You’d be surprised at what comes out of there.

I see no issue with your plan. I’ve removed the rubber bushings on my slide pins many moons ago. 2020 RAV4.

Funnily enough, I used my Mossberg cleaning kit to clean out the bores lol. Sprayed a bit of non-chlorinated CRC brake kleen, and cleaned it out. The slide pins themselves, I wiped down really good with a microfiber. I did not want to mess up the coating on the slide pins by using anything else.

The brakes definitely feel smoother. I have to do the fronts next.

I almost mentioned brake cleaner. I have nothing else to add, you did exactly what I would have done.

If this is the same as Toyota soap grease or whatever they use at the factory, then I would return it. 7 out of 8 pins on my CH-R were seized solid and required quite a bit of force to free up at only 25k miles or so. The grease was not hardened up though, so I don't know what's going on.
I only checked because another poster here had the exact same issue on his brand new Toyota.

Get yourself Mission Silicone paste, it's back at Amazon.

This is one that I used “Toyota Rubber Grease 08887-01206”. Is this the same one that seized your pins?

I don't know other than it was factory grease because the car never had its brakes serviced. It wasn't pink though, more like white lithium grease.

From what I understand, the pink rubber grease “can” turn brownish overtime. I wonder what was used in your CHR from factory?

Found the thread that prompted me to check the pins. Just because it's Toyota branded, doesn't mean there aren't better solutions.
I've been doing my brakes for a long time now and have never had a problem like this with quality silicone grease.

Thread 'Rav4 Brakes - Premature Wear due to Winter Conditions'

Oct 6, 2024

Our 2022 Rav4 Hybrid has about 45k kms (28k miles) on it, and we have owned it from new. It sees very harsh winter climate with lots of snow, moisture and salt. I took the brakes apart this weekend to service them and the front brakes were very unevenly worn. The front caliper pins were seized up, despite the fact Toyota serviced them about 1 year ago. The inboard pads are probably about 75-80% worn, while the outboard pads are only about 10% worn. So I will likely have to replace the pads sooner than later, which is very disappointing life - the shortest brake life I have ever had on...

What uou did is probably fine. If it were me, I would be curious why the rubber bushing did not fit. I've replaced the pins/bushings on a Honda and they were fine. I think I used Raybestos pins.

When I fitted the slide pin bushing on the slide pin and inserted it into the bore, it went in but it was tight, even with the Toyota pink rubber grease. The bore isn’t warped nor does it have any rust or damage inside so I’m not sure why. I even swapped the top and bottom slide pins and they fit equally as good minus the caliper bushing issue. I have read some threads from Toyota Nation where people with 3rd Gen Camry’s like mine, had issues with warping rotors every couple years. I wonder now if the bushing was the cause. When I bought this car 2 years ago, all 4 factory rotors were warped.

I have usually been able to clean the bore with brake cleaner (fill the bore with it and let it sit for a minute or two) and a Q-Tip.

Get Mission Grease.

You should be OK without a busing on one of the pins, but my guess is a pin with a bushing would fit OK if the bore was really clean.

 

[jjblbi]

I've always cleaned the bores and then applied hi temp silicone grease to the slide bolts. If you look closely at the bolt with the red arrow you will see 'flats' machined into the sides, these hold a reserve of grease.

I’ll have to get either Mission or Wurth. I’ve seen Wurth Lubricating compound aka grease after 50k miles on another post, and it was still on the pins. Pretty impressive. Otherwise I just have to use this lithium glycol stuff Toyota’s calls for and service it once a year.

I saw those on there. The Car Care Nut mentioned the same thing you did, as well as they function to remove air from inside of bores.

I've had good luck with this grease from NAPA.

That’s the one I used which caused these issues. It was non-existent on the slide pins after 4500 miles

I used to use anti-seize and switched to Sil-Glyde about 15 years ago. VWs, Audis, Ford Escape and Ram trucks, no issues. All those caliper slides did have the machined flats.
