Replacing rear caliper bracket without the caliper

Caliper and bracket are separate items here:


REAR DISC BRAKE CALIPER & DUST COVER. 2013 Toyota Prius Hatchback | Toyota



Not cheap though.

 

You should be able to unscrew the pins from the caliper bracket and buy a pin and rubber kit it'll be the slide pins and the rubber bushings and probably a pack of grease might want to get upgraded grease I just like $9 a caliper or something or bracket pretty inexpensive or you can even tap them off with the hammer the calipers that is get your Dremel out with the wire wheel what have you and you can buff them right back up to clean I've even buffed pitted ones that were really bad before you could buy these pins clean them up grease them up clean out the rubber and the piece that fits into and regrease and put it all back together I don't put it together until I can move the slide across the pins with my pinky finger if it doesn't move that easily I clean it and redo it again until I have it where I can push it with my little finger and that slide goes all the way out and pulls all the way back with my small finger then I know it's going to stay on there another hundred thousand without sticking generally speaking

 

One saving grace, the bracket is symmetrical, same part number for left and right. A person wanting a spare on hand in case an old one got too rusted up would only need one spare.

Not so for the fronts; those have left and right brackets.

 

Puzzling: the bracket costs over $25 USD more than the caliper. Vagaries of supply and demand I guess. And the "lifetime" brakes mindset.

 

Probably expensive because the pins and rubbers are available and most people probably buy those in the fast moving part section rather than buy the whole slide or bracket or whatever you want to call it if I'm not mistaken I haven't personally looked up the Prius but my Corolla and Camry have replaceable pins or slide pins or whatever you like to call them.

 

What do you mean by "stuck"?
It won't turn so you can remove it?
Or you can get it out after loosening it.

The simplist was is not really to replace the whole thing.....
It would be to figure out why it is not "removing" and then remove it, if possible.
Then remove the boot and clean both and lube them.

 

Wow. I had this same question about 3 years ago. I was constantly getting uneven brake pad wear on my rear brakes, so I wanted to replace the brake caliper bracket in hopes the pads would wear evenly. I changed everything from the caliper lube, to the brake hardware and even the caliper pins/boots and grommet at the bottom of the pin. I eventually decided it was worth replacing the caliper bracket.

Well, I did find the brake bracket sold separately at the dealership in Canada. The problem is that the dealership bracket price was greater than paying for the complete replacement with an aftermarket caliper. The price of the OEM complete caliper assembly at the dealership was just ridiculous. I can't remember what price it was but it was about $300-500. I hope you find a better price.

I ended up buying a whole Raybestos caliper assembly from RockAuto. I got it installed by a mechanic for a cheap $60. It has been working well for the past 3 years (but with minimal driving during COVID19). It worked for me, but it didn't work another poster in Montreal, Canada:

I also lost a set of brake pads due to a stuck caliper pin. It was heavily rusted in there. I managed to wrestle it out of there by twisting and pulling until the scraps of rust came out. I sanded all the rust out and replaced the pin. Maybe yours is stuck in there forever. Yes. This is the same caliper I replaced in the end.

 

That reminds me of my experience with an aftermarket caliper.

I would now perform that piston-return test on any such caliper, on the bench, before the effort of installing it in the car, to avoid that kind of headache.

 

When I had a stuck pin that ultimately sheared off in the bracket I drilled out the bore and bought a new pin.

 

Your post (aftermarket caliper) is a rare one. I once read or heard about the gasket acting as spring and i bought it right away. Made sense. But try to explain to someone..or find from chatboards Interesting that Toyota explains it thoroughly in shop manual.

Kind of same as trying to explain someone that a bolt joint is about friction and bolt is just a spring creating the friction

 

If I remember right, that illustration isn't from the repair manual, but from one of the "University of Toyota" technician training modules on disc brakes. All of those materials are also on TIS, same place you find the repair manuals.
