Ok, after adding the 4-pistons calipers from a GXL, I was told I need the check valve on the MC. Do I also need the GXL booster? I have one available to purchase, but I'm not sure if I need it.



So, what exactly do I need?

I would use the ENTIRE brakebooster,mastercylinder assembly from a GXL

If I am upgrading my GTu from single piston to four piston calipers, I should change out the booster and MC also?

banzaitoyota

yes

Nemesis

Got any extras laying around?

banzaitoyota

Unfortunately , no. I need the last set I have for the Base upgrade

thanks for the info, banzai. Does anyone know what kind of price these things should run? I know a guy with the parts, just making sure he doesn't overcharge me.



also, any idea what level of difficulty swapping these would be?

The master cylinder is no biggy. With the proper tools and a pressure bleeder you're done in under an hour. I've never swapped a brake booster, but that should not be hard as well, since you alreay will have the MC off.



I bought a new master cylinder for $70 shipped from www.nopionline.com



It is brand new in the box, made by Tokico. Even has the MAZDA part number on the box.

cool, I'll offer him no more than $50 for both parts (used)



I looked over the removal of both items during breakfast this morning (in Haynes manual). The seem pretty simple, like remove brake lines from MC, remove 2 bolts, it comes off. Booster is like a tube, and 4 bolts under dash. I may be off a tad, but it doesn't seem difficult at all.
