Just did my front brakes

replaced my pads and rotor on front 2015 taco- they were glazed over but not bad- going to have rotors turned for next time. the pins as you see were pretty much welded in at 75k miles. I pulled the tires and tried to tap the pins out to no avail. I then liberally sprayed them with kroil penetration oil. I left it for about an hour and they tapped right out. expensive oil but I think well worth the money. first time I ever used it. btw I do live in the snow belt

 

Nice work. I apply a bit of synthetic grease to my pins every now and then.

 

I did put anti-seize on them during reassemble

 

Kroil is one of if not the best penetrant

Green brake grease might be better for the slide pin because it moves and doesn’t have abrasive grit.

the whole caliper looks done for. Pins can be replaced or cleaned on a bench grinder with wire wheel.

 

I changed the rear pads on my wife’s Camry and I think it’s the only time I didn’t use PB Blast a couple days before, those bolts were stubborn!

 

A set of replacement pins is a pretty inexpensive spare. Use high temp grease to lube them ......... you can get little packets at the parts stores.

 

Why grease the retainer pins? It just attracts dirt. They don't do it at the factory and those brakes last 60k. They just need to be clean

The only pins that need grease are the true sliders on a floating caliper that have a little rubber boot cover on them. Anything that isn't covered by a boot is just going to wash off in a week anyway

 

First time I disassembled these - I discovered the Toyota pins were rusted and covered in crap. Had to knock them out with a pin drift. Probably assembled dry with no anything (as suggested?). Replacements were coated with "bright zinc" plating - maybe 1/2 thou if we're lucky.
My initial years of use of the truck with dry pins resulted in "rusted and covered in crap" - so maybe something better might be tried?

 

I've noticed that the mag chloride that is on the roads here in Colorado do a number on certain metals under our cars. I've used PB blaster in the past as well with good results. Also recommend trying Seafoams Deep Creep. This stuff worked fast on a couple of cruddy bolt projects that I had.

 

So. With a caliper that corroded, how's the frame look?

 

In my part of the country, the Adirondacks, rather than try to clean and lube the slider pins I remove and dis-guard them. I check to make sure the pads are free in the caliper and replace the pins every tire rotation (every 6000mls. for me). For the cost and as quick as they seize up in this winter environment it worth and easier just to replace them.

 

scott in the lake george area here

 

Saranac Lake. 1 1/2 hrs north of Lake George

 

I replaced the pins and did use brake grease on the slides after wire brushing

 

been there

 

frame is good- I been all under it and it has been in the shop for frame inspection and has been "sprayed" service at the dealership
