Brake Upgrade: StopTech Rotors + TRD Performance Pads

I used sta-lube brake lubricant at recommendation first time around

 

That looks like a lot of lube. You greased them the first go around and ended up with squeaking? Did you discard the original anti-squeal shims, so that you are only running the TRD shims? I don’t typically run lube on the back of my pads.

 

In the early 90's, during college, I had a summer job wrenching at a great foreign indy garage. I learned sooo much there, wouldn't trade the experience for anything. Anyway, the owner/boss introduced me to CRC Disc Brake Quiet in the aerosol can, he did not want comebacks for squeaky brakes... very much a do it right the first time type of guy. A can has been in my tool box ever since.

 

What you see in the pic is just the TRD ones. I just put the drive side back together gonna check passenger now

 

That’s what I thought but just checking. Brake squeal can be very frustrating. I don’t have a lot of experience to offer with different lubes to fight squeal as the shims alone typically work for me. I’m assuming you have also bedded the pads?

 

Yep I will try again after I relube...just wanted to make sure I didn't f up.

I did bad them quite well and it definitely has crazy bite

Just sounds like they're old pads

 

Unless the sound is displaced and it's actually the rears because I used the e-brake poor 150 MI

 

Your speech to text is all sorts of fucked

 

tratando de changing from English to Espanol

 

See what I mean

 

Ok regressed it all. To include the little w clip that holds everything in place. Took it for a drive no squeals so far. Here is hoping it's gone.

Bite still there.

 

This upgrade is pretty great. Just got them installed last Sunday with the help of a local member @whatstcp and I couldn’t be any happier with the improvements. We even did a full brake fluid flush and I have a firm pedal again. And no more steering wheel shimmying when braking at highway speeds. If your on the fence about this upgrade don’t be it’s well worth it. Thanks @crashnburn80 for providing such detailed information as always.

 

Thanks for the write-up @crashnburn80.

 

@crashnburn 1st off, great post and great thread, tons of info here. I've been considering the same kit, sticking with 17's. So you are still currently running the stoptech 340mm 6 pistion? Only modification you had to do was acquired a larger splash shield from a 5th gen 4R? Other then that, it's just a direct bolt and no other issues like what alexplb was having and ended up going back to stock?

 

Correct. I was a bit concerned with pedal travel using 6 piston calipers, but they are sized appropriately so it is a non-issue. You don’t have to use the 4runner dust shields, the kit comes with a thin spacer that replaces the stock shields in the hub assembly, but then you’d be without them. I opted to use the larger 4runner shields instead and not use the spacer.

I wasn’t super impressed with the ceramic street pads initial bite compared to the TRD pads, I’m going to swap them for the semi-metallic sport pads.

I see SOS updated their brake line listing, when I got mine it said up to 2” lift for the standard lines, so I got the next size up and they are way too long. Definitely go with the standard lines unless you are long travel.

 

The thin spacer that replaces the stock shield, if it take away the factory shield, what's the purpose for it? Im currently in the works of getting my lift in, so i ordered crown lines front and rear. The oe brake line setup has a hard line off the caliper then rubber section to another hardline. For the lines that come with the ST BBK, it replaces those 2 sections of the existing brake lines (mounting at the caliper and rubber lines)? Ending up with just a single line directly to the hardline of the system yes? Sorry just trying to get a better picture of this setup

 

The spacer is to keep everything lined up in the factory location since the parts on the hub stack together. Yes, the StopTech lines are specific to the BBK and replace the hardline off the caliper and the rubber line. The new SS lines run directly from the caliper to the hard line on the chassis. The StopTech BBK uses a different sized brake line attachment point at the caliper. You will not be able to use other aftermarket lines that fit the OEM setup, or reuse the OEM hardline off the caliper. I tried since my StopTech lines were too long. You have to use the included StopTech brake lines for the BBK kit.

 

Appreciate the help!!

 

The ST60 calipers use the FMSI D1247 pad... if you want to go outside Stoptech for a compound.

The main body number of Stoptech/Centric/APC pads is the FMSI pad shape number, the prefix numbers are the compound. Ex. - The Street Sport Pads for the ST60 Caliper are 309.12470.

FWIW, the TRD Sport, along with the Stoptech 309 and 306 Series compounds are all the same. The 306 is sold under the HD Fleet name, and can typically be purchased for less than the other two, just in a different box. They are a bit hard on rotors, but really there when you need em'.

 

The TRD and StopTech 309 Sport compounds are the same? Based on what I read I thought the StopTech Sports were semi-metallic, but finding actual data or real product info on StopTechs site is horrible after being acquired by APC. All the previous tech info now just forwards to a dumb down marketing product pages. That at least validates my driving impressions that the StopTech Street pads do not have as good of initial bite as the TRD pads.
