Different sizes of rear brake floating caliper guide/slide pins

Why are there different sizes and where to put them. What is their purpose?

Have you ever wondered why are rear brake caliper guide or slide pins are different sizes in the floating caliper braking system? Some manufacturers of course will have the same size caliper pins, but many will have different sizes of these guide or slide pins. This video will try to explain why they are different sizes and where to put them or in other words which goes to top and which goes to bottom. More accurately I will explain which one goes to the leading and which one goes to the trailing position.

The car is a peugeot 307 1.6 petrol version (TU5JP4; 2008), but this is applicable to a lot of manufacturers, especially Honda, although the brake bracket is in the forward position rather than at the rear of the braking system. This video is for rear right of the car.

Not confusing at all!
I'm sitting here watching your video and staring at these two pins and now I know which one goes in the right spot! I learned something today!

Lots of people can do. Few people can teach. You're a good teacher, well done! 👏🏾👏🏾👏🏾

[Boffin]

Nicely explained, thank you!
I was scratching my head after I took the Calipers/Pins off my Audi A1 but didn't notice the pins were different till I came to put the new ones 😃

Great advice, I was perplexed when I cleaned the old sticky grease. You saved my day. Thank You, very well explaned.

Great video and great explanation. Would love to see another video expanding on this topic when one pin has a rubber sheath (damper) on it. I've seen videos where mechanics say it's fine to just remove the damper after it's expanded/old and is preventing the pin from sliding/moving easily. Others say you can cut/shorten the length of the damper. Thank you for your time in making and sharing this information with everyone.

Your the only guy on you tube that made sense of the different pins good job

[annajackson]

Thanks for video. I was cleaning caliper sliders, noticed difference in pins but could not think of reason. I now know.

[zimnyleszek]

Great job for explaining Many people confuse why slide pins different . 👍

[Networkprofessor]

I hope I saw this video before I did my brake job. I realized this after I finish the brake job. This video prove that I was right. It is too bad I listen to all those people who made video on this subject.

Very well explained, Thankyou.Ford Transit ones have a rubber sheaf on one of them.

[claybourne]

Thank you for the explanation on the different pin designs!!

On my 2021Toyota C-HR, the difference between the 2 pins is that one pin has a bushing on the end of the pin and the other pin doesn't. The pin with the bushing always goes on the trailing edge for both front and back calipers. So for my car, the position of the pins are not chosen to make pad replacement easy to do where only one caliper pin bolt is removed and the caliper is flipped upward. The positions of the pins may be chosen by the manufacturer only to allow the brake calipers to function more efficiently. Thanks for your video.

Thank you for video.

I do have Honda Accord 2000 ex v4. Recently I did some service of the brake parts. The caliper is mounted on the front side. On one wheel, I was confused with the pin with rubber sleeve. When I went to the second one, the pin with rubber pin is located on the top. Now the steering wheel vibrate at high speed and braking. Do you have any idea about this?

Thanks

[iansmeath]

Thanks for the information in your video this helped me a lot!

[azerahasgotachannel]

So leading is the fatter one and thinner one is trailing?

[Skodra]

Can you explain pins with rubber ring at the tip of
One sliding pins?

[abdangry]

mines are both hard to push in, the leading one doesn't bounce back when i pull it out is. do they need replacing or that's how they're supposed to be?

[zteburner]

Great video... Thank you. Do you know why there is a rubber boot on one of the two? And on my rear right, the top siezed after 60k miles. Need to figure out how to remove it.

[domos]

If the calipper is located closer to the rear bumper, should the guide with the cone be at the bottom? Yes?
