4th Gen Brake Upgrade Glock_19 by Ducmonsta

[WXman]

I'm considering ordering parts to do this mod, but the bare minimum is $300 to do this, and quite a bit more if you use higher-end parts.

So I'd like to hear from people who have done it, did you instantly notice a large difference in braking? Or was it a subtle difference that was kind of hard to tell?

Major diff ive noticed is that after alot of high speed stops fade and pulsation are not a factor where with my smaller wg calipers I would get a pulsation after alot of highway driving. But as far as stoping power ive noticed no difference.

Realistically, this mod should be done when you need to replace the brakes. Not because you want to upgrade them. There really isn't a huge performance gain.

Well I am coming up on 115K and the brakes as far as I know haven't been touched since around 70K when all 4 calipers were replaced/rebuilt due to seizing. So pretty soon I'm going to have to do a brake job regardless. I was just on the fence about whether to dump the cash into this mod or not...but I think after what you guys are saying I'm going to hold off on it and spend the money elsewhere. I still have to do CVs and ball joints this winter anyhow.

when i did mine i needed the calipers anyway and the wh calipers were actually 6 dollars cheaper than the stock wg and rotors where just about the same cost. pads are the same

So... does it seem worth it at this point?

If you gotta change the calipers anyway than yes its worth it because you reduce the chance of warping a rotor if your gonna do it just to do it then I would say no

 

[earthrealm]

no noticeable increase in braking.....did it cos i was tired of servicing the calipers....and i had one bad rotor...so i decided to swap out every thing and keep the 13wg calipers and rotors as spare

I've read somewhere that the Sport Editions have a bigger brake set up. Would this Tundra set up happen to be the same?

Don't drilled rotors crack easier, though?

Yes they do. I didnt use drilled rotors I used stock sport edition rotors and wh calipers. My limited had the smaller stuff on it from factory

OH, so you just upsized? I guess OP went with drilled.

After trimming the backing plate and painting, this is what you'll end up with.

I just completed this yesterday. Great write up! I did not paint the backing plate though. Think that will be an issue? I didn't because it would be very tough to cover the entire plate without overspraying the nearby components. I did clean it with brake cleaning fluid.

did it by accident...

So, I inadvertently did this upgrade. I have a 2003 limited v8 and assumed that with the 17 inch wheels I would have the bigger brakes. NOPE! so we already had the bigger rotors and the bigger calipers, plus the smaller rotors and calipers were not in stock and cost more... So, my dad and I just decided to give it a go. We did not have to modify the backing plate, just pushed and bent it back a bit.

I dont notice any difference in the stopping distance like I did when I did the WJ brake upgrade on my jeep. That was going from single side single piston, brake calipers to 4 piston brake calipers... big difference...

All in all this is one of the easiest "upgrades" that I have done so far...

Use Rockauto.com if you are able to wait. I spent just under 200 for calipers and rotors at Oreilly's. I already had new pads, just stuck calipers...

No noticeable difference, just do it because the parts are cheaper and available...

For the guys who have done this upgrade: are you experiencing less sticking calipers with this setup? I'm getting tired of doing a brake job on this thing (what seems like) every summer....

I'm not overly concerned with better performance (not that I'm against it) but I'd really like a set of calipers that are less prone to seizing up.

Not really, they seem to be just as prone to sticking because the calipers are the exact same design, the only difference is the mounting points are extended a bit.

poop. that's what I figured...thanks.

So I've got a 2008 Limited; this wouldn't be an upgrade for me? But the 5th gen is a mild (rotor) upgrade?

 

[Cammer]

So... does it seem worth it at this point?

I know this is a very old thread, but I need to add some information.

The difference between the two rotors is significant.

Surface area of 319mm standard rotors = 123.8 sq inches
Surface area of 338mm sport rotors = 139.1 sq inches

This is a difference of 15.2 sq inches, which is a 12.3% increase in swept braking area. Also there is greater mass (larger heat sink) which decreases brake fade. Heat is the number one enemy of brake efficiency. Larger rotors will provide lower peak temperatures and longer wear cycles between brake pad changes (lower maintenance costs), as well as significantly better braking ability during times of frequent hard braking - mountain roads, etc.

The Sport brake upgrade is definitely worth doing.
