Just from my lessons learned from my old Tacoma- if you want to avoid rebuilding the calipers while the truck is still less than 80k-100k miles, make sure to just purchase the correct piston compression tool for the front calipers. Don't do the screwdriver prying against the pad method that a lot of KZreadrs still show. As shown in his video, the piston walls DO accumulate containment and buildup over time (partially because of the outer fluid channel in the caliper), and the screw driver method causes that stuff to foul up the piston/seal interface, it may slow down just one piston. This eventually causes uneven, unlevel pad wear by a very small amount, and then will cause a runout on the rotor- and as a result causes whole truck shakes during light braking despite having very smooth hard-brake performance. The piston spreader assures that the pistons are returned all the way in while staying perfectly square with the caliper. Multi piston calipers are great, but they are slightly higher maintenance and they all need to be moving evenly with one another to always allow for perfectly level pad wear. Needless to say, I rebuilt those calipers, and then replaced all the hardware again because of the runouts, and they performed even better than new without any problems.

Replacing the Banjo Bolt with new washers is a great idea. I did my brakes and calipers without replacing the Banjo Bolt and washers and shortly after every one of them leaked. I'm not saying that will happen with yours but that is what happened to mine. GREAT VIDEO!

Well, for sure the washers are supposed to be replaced. In the Toyota FSMs, they are always considered a non-reusable part. But, the banjo bolts are reusable. There's not a lot that can go wrong with them other than getting plugged with gunk. So, I view the banjo bolt replacement unnecessary. But, to each his own. The bolts aren't expensive, so replacing them isn't a huge expense. Glad you like the video Rich.

If you are reusing pistons with any corrosion, you want to put the piston in with the discoloration up. Opposite the staining in the caliper. The rust/stain/deposit always forms on the botom(as installed), because water that creeps in through the seal from the atmosphere collects on the bottom. Also, "brake caplier assembly fluid" is the best shit ever made. It's not hydroscopic. If this is a car you don't often drive, its mandatory.

Hey Andrew, thanks for the information contribution.

I use very fine valve lapping compound with a cloth to clean up the pistons, works a treat.

Tim/Sean, another great video! I spent a lot of time in the Bay Area before leaving California. I love it how you travel to people’s homes to film. He definitely tested those brakes when he left his driveway. It would have been mildly funny if he went across the street into the dry grass. I am glad the rebuild was a success. Take care.

Another great video. I found your advice on getting the pistons out very encouraging because I don't have a compressor. So I assumed I wouldn't be able to do this job. But seeing your video changes all that. BTW I've done 2 valve cover gasket jobs on 5vz-fe rigs in the last month and both went perfect thanks to your channel.

Thanks! I'm glad you liked the video. Yeah, the air compressor trick to get the pistons out is more of a pain in the ass than it's worth, in my opinion. I suppose if you had the perfect progression of blocks and shims to get the pistons protruding out of the caliper fully, it wouldn't be bad, but we found we'd end up getting one piston that would shoot out too far and then we'd have to push the piston back in and reset. When I finally went to the screwdriver, I realized it was way more straightforward and easy to get the pistons out of the caliper. It's great to hear our videos are helping you out. Thanks for the comment, and Happy Wrenching!

Thank you Tim! This is another great point of reference. I will be rebuilding 2 sets of Tundra calipers; the 199mm, & the 231mm from a Sequoia. I just got them all cleaned up and ready to paint! Both factory kits are the very best; however, you still need to keep the inner seals to reuse them, because the factory kit do not come with these. Take care Brother!

@TimmyTheToolman

10 ай бұрын

You're welcome. I'm guessing the inner seals you're referring to are the ones that seal the caliper halves together? The piston seals should be replaced and are included in the rebuild kits. I had heard from another person that if you don't have to crack the calipers apart, don't. Toyota doesn't sell the o-ring seals.

Very detail video on caliper rebuilt. I used this as a guide on 04 4runner, but 2 out of 4 pistons on both front calipers seized up and had to buy rebuilt calipers from Napa. One question though, why the rebuilt kit comes metal rings for pistons boots? The original calipers on my 4runner only have rubber boots on the pistons and they were easy to remove.

@TimmyTheToolman

8 ай бұрын

The metal rings help keep the boots in place so they don't slip off.

I bought some repackaged pads from Amazon and they had the squealers on both pads. They were new but I paid less than nine dollars for the set. My buddy said I got a deal because he said you can’t put brakes on a bicycle for less than nine dollars. 😀

Great timing. My dust covers are looking a little ratty so I need to do this before the pistons start sticking. I got the OEM kit but no grease. I assume I can just use a little brake fluid. Or should I use the same hi temp grease that I will coat the pins with?

@TimmyTheToolman

8 ай бұрын

I don't know what type of grease that is that comes with the kit. I think the high temp caliper grease would work fine.

It's likely that the small amount of corrosion or contamination to the pistons and inner cylinder, didn't get past the seals, but came from moisture in the brake fluid. Most brake master cylinders are vented to the outside *and* brake fluid is hygroscopic (absorbs moisture), which is why the brake bleeding maintenance intervals are pretty important to follow closely.

@TimmyTheToolman

Hey, that's a very good point. The brake fluid can develop moisture in it over time and that's why it's important to renew the fluid at regular intervals. Thanks for sharing this.

I know I learned the hard way on my Tundra put the wear indicator on the OUTSIDE not the inside pad. My outside wore before the inside and ate into the rotor before it squealed on me. Toyota should put indicators on all pads IMO.

@TimmyTheToolman

10 ай бұрын

I really think it's luck of the draw which side you put the pad with the wear indicator on so you catch it before you go metal on metal and destroy your rotors. I absolutely agree with you that Toyota and other manufacturers should put the wear indicators on all 4 pads.

@@stevanrose7439 Yeah, that sounds like a great deal. Most of the aftermarket suppliers of brake pads adhere an anti-squeal shim onto the back of the pad. Toyota does it differently. The pads come separate from the shim kit and the shim kit is made up of two shims, one slotted and one solid. But, the Toyota shims are reusable. Most people who replace their OEM pads with aftermarket pads, throw away the OEM shim kit, which is a mistake, if you ever want to go back to OEM pads.

Lightly polish the area where the sides of the pad sit for free movement

@TimmyTheToolman

I'm guessing you're talking about polishing the inside of the caliper on either side of the pads? There really shouldn't be any interference there, but I guess if there's a build-up of corrosion in that area, knocking it down with a wire brush would be advisable. The crucial things to make sure are smooth are the retaining pins the pads ride on.
