RockAuto is running a 10% off promotion on Advics brake products for all of April 2024. The master cylinder reservoir will say Toyota on it, since Advics supply them. Looks totally OEM in all respects. A BMT-360 ABS master cylinder will cost $88.01 after rebate. A non-ABS BMT-106 master cylinder will cost $50.21 after rebate. The rebate shows up instantly in the shopping cart. It's great to find a brand-new OEM part at a reasonable price. Take that eBay parts pirates! While you're there, you might as well look around for other things to make the shipping worthwhile. Fel-Pro valve cover gaskets are a good choice along with their exhaust manifold gasket. Let your budget decide how far to go, but stay away from brands you're not familiar with. One thing you're going to need from the dealer is the paper gasket that goes between the master cylinder and the brake booster. The part number is: 47275-24010. To be thorough, you should have the tool that measures the distance that the brake booster push rod should go into the master cylinder and check that the one sticking out of the brake booster is at zero clearance. You can pick up an inexpensive copy on eBay or rig up something yourself. Here's a link to the online method:

It's advisable to bench bleed the master cylinder before installation either by using plastic screw in adapters, or twisting in some clear tubing directly where the 2 exit pipes go and looping it back into the reservoir. Fill the reservoir with brake fluid. I like Valvoline DOT 3 & 4 synthetic. Carefully and slowly push the plunger completely in with a blunt shaft enough times to expel all bubbles. Temporarily plug up the exit holes and put a towel under where you're working to avoid dripping brake fluid on the paint. It's best to use a flare nut wrench when working with hydraulic lines to avoid rounding over the nuts.
