This is an old video with millions of views and tons of comments, but if you do see it, how would remove a pin that was truly completely seized? As in it doesn't move at all, rebound, twist or anything. I think the pin is gummed in so hard like cement or something. It might take a ball peen hammer or something to get it out. I don't think i can remove the pin without possibly damaging some of the hardware (caliper. Since it's the front caliper, it doesn't separate from the bracket, and i'd rather not have to replace the entire front caliper assembly, which would also entail bleeding all four wheels, making a relatively cheap and simple repair to an much longer and expensive one. Thanks for your videos; you do great, impressive and easy to follow work, explaining it very well.

Thanks for the very appropriate reminder about inspecting the caliper pins. On my last brake job I found the rear guide pins were all almost seized. I removed all four and cleaned them, using some 120 grit sandpaper to remove the worst of the rust - then some 400 grit paper to polish the pins. BEFORE reinstalling them I also used break cleaner spray and a cloth to clean out all the old debris from inside the caliper. I've also used a steel drill bit of the correct size, turning it by hand ONLY, to get as much dirt/corrosion out as possible. Once that was done I used the silicone paste to lube the pins and install them. My brakes worked like new.

The other thing to remember about your slide pins
when youre doing the brake job theyre at room temperature and whilst they feel okay you dont know how they feel when theyre red hot because theyre too hot to touch
so youre well advised to always lubricate them to make sure that when theyre at operating temperature they still have the best chance of moving which is a different story to room temperature.
Dont forget metal expands if theres any junk between the pin and the bore that stuff all expands
it might feel okay at room temperature and when its hot it might be jamming.

Hey Chris. I have a question. I tried to change my brake rotors on two of my cars. When I took the bolts out, one would not seat right and and even when I installed the bolt by hand the torque it, it would not go in fully and started to cross thread. I'm not sure why this happened on both my cars as these are new cars and the first time the bolts would have been removed. I bought new bolts and still, the thread was cross thread inside the caliper. How can I prevent this? Why did this happen? Could it be that it was already cross threaded when it was built? Thanks so much.

Chris, please help. My slide pins looked exactly like yours, bottom one fine, top one stuck. I replaced the sliding pin and rubber because even after cleaning off the old pin and hole where it slides in to, it wouldnt go back in. But, even with the new pin with silicon grease, and with cleaning out that hole with a pistol cleaning set, I still can not get the pins to slide in and out! I ended up just hammering it in so I can use the car. But do you have any idea what else I can do? I may just have to replace the caliper: /

I do my own brakes and have since 1989. I will smoke any brake mechanic out there all day everyday.
Most brake places do shit work. Slap it together get the money and go. Not here i take my time and its right including bleeding the brakes everytime. Midas and the others can hit there knees.

I recommend wearing ear pro if you have to bang a really stuck pin out. Last fall I had to do this on an outback and the pinging of a hammer on a lug wrench for 10 mins made my ears ring for the day.

Good video. I would put some grease inside the rubber boot b4 putting guide pins back in. If you only put it on the pin the rubber boot removes most of the grease from the pin like a squeegee

Thank you for your videos Chris! I noticed at 3: 17 that your lower Guide Pin Boot has a tear in it - best to replace it now before it totally corrodes the Pin - been there, done that! :-)
