ST204 to Avalon Caliper, Single to Dual Piston Options

[ILoveMySilly97]

This thread is to clarify all the confusions of this swap. Here's the common Qs and As.

Q: Are they BOLT ON? Meaning the stock pads and bracket will work?
A: Yes they are. They're a direct bolt on. No modifications needed. Everything will work with it. Pads, bracket, brake line, rotor, etc. etc.

Q: Do they fit the ST(AT200) models?
A: No they don't fit.

Q: Which year Avalon?
A: Only the 95-97 Avalon W/ABS has the dual pistons. The ones w/o ABS are single piston.

Q: Does the Camry V6 or the ES300 Caliper bolt on too?
A: More than likely yes. I never done it before so I can't say it is bolt on.

Q: How much did you spend on the swap?
A: I spent $41.68(the set of caliper from a local PickNPull) and $7.68(rebuild kit). This swap shouldn't cost more then $60. I also spent another $15.03 on spray cans to respray it.

Q: How hard was the swap?
A: It's bolt on so as long as you know how to turn a ratchet or wrench. Then it's an easy job.

Q: Was there any noticeable difference in braking power?
A: Yes there was. It's a lot more smoother feel and a little more stopping power.

Below are going to be some pics to compare the GT vs Avalon equipment.


Avalon rotor on the left and GT rotor on the right. As you can see the diameter is the same as the GT rotor so no problem there.



Avalon Caliper on the top and GT rotor on the bottom. The Avalon has a bore of 43x2 = 86mm total. Vs the GT which only has 57mm. So that's a difference of 29mm! Which is close to half more bore size of the GT. Also note that both pads are the same number. So that's a direct bolt on.


Here's some pics of my GT brackets mounted onto the Avalon Caliper.


Here's a pic of it actually mounted onto my car. Direct bolt on.
