Help on deciding on brake master..

[82 Lover]

so im ordering parts from rockauto and i need to make sure i order everything at one time to save money on rip off shipping to hawaii. LOL.

but im ordering stock master from dorman. because wagner and dorman are basically the same.

1. But are they actually good?? 2. what is another route i can go??


I hear people are putting on the mk3 ones but they said they loose feel in the peddle... i dont want that.


I am also ordering all new seals since i took my donor set of calipers apart. sand blast, repaint.


And if u have new stuff leying around. ill probably buy it. LOL

I wouldn't trust Dorman after what I've been through with them. I bought a brand new master cylinder for our Chrysler minivan because I thought remans would be trouble. Got it on, test drove it and it was good. The next day we took the van into town, and the brakes started locking up! Each time the brakes were applied, the pedal got stiffer and the van got more sluggish. We had to turn around and go back home (5 miles) with the front brakes partially applied. Had to run a stoplight because if we stopped, I was sure the van wouldn't start moving again. It was a hot day with no air conditioning and the kids in the van, so we HAD to drive home. By the time we got back home the front brakes were SMOKING and the air was filled with the stench of burned brake linings.

End result was ruined pads, rotors with brake material melted to them, calipers with melted rubber seals, and probably fried the grease out of the front hubs. Half of the master cylinder was sticking and not releasing. I got it to release once by bleeding fluid from the master cylinder at the lines. I grabbed my wrench and headed off on another test drive. The brakes started locking up again, so I had to bleed the front line again to get back home. Went out and bought a remanufactured A1 Cardone M/C from O'Reillys, swapped it in, and returned the POS Dorman M/C. Had to get new front brakes from U-Pull-It and miss a week of work getting the brakes all fixed up. Still ended up replacing a front hub that winter.

I would have preferred a Raybestos remanned M/C based on their manufacturing facility and certifications, but I needed parts that day and had to buy what was locally available.

As for the MK3 master cylinder, it just adds a little extra effort to the pedal and applies the brakes faster. I put a 2001 Toyota Tacoma 4x4 M/C on my black supra and it works great (it's also a 1" cylinder). I do plan on putting bigger brakes on the car (Infiniti Q45 calipers front, Cressida calipers rear) that will take extra fluid to apply.

thanks for that note road! did it need any extra fab. or pretty much bolts rite on to the booster?

I would get an AISIN/Advics brand if you can. I heard CARQUEST and WORLDPAC has them for sale. AutoPartsWAY.com and AutoPartsWarehouse.com has them for sale too but make sure its for a Celica Supra and not a Celica. I think one member ordered from one of these websites and received the brake master cylinder for a Celica. You can confirm by which side the ports are on, the ports should be on the drivers side for the Celica Supra. Let me know if you find out who sells the AISIN/Advics brand because I have not found anyone selling it yet, I know it is out there though because some members said they have bought one in the past before.

If you get a RAYBESTOS brand from RockAuto, make sure you paint it before you install it. If you do not paint it, it will start to rust right away.

Toyota also still has brake master cylinder rebuild kits available. This is another option, but I heard from Mark that people who have tried to rebuild their original brake master cylinder has not had very good results.

The Tacoma M/C bolted right on to the booster. The 4Runners and 4x4 trucks also use a 1" diameter M/C and will bolt onto the booster. My Tacoma M/C is aluminum, so no fear of rust. A coat of clear paint would keep that white oxidation from appearing, although brake fluid from hooking it up would eat off some of the paint. I did have to bend a new line for one of the lines, and just tweaked the other line to make it fit.

^ Hey good to know if I ever gotta swap the Supra one out! haha.
And sadly there are tons of 96-01 Tacoma's in the yards to pick off of... stupid recall
Funny cause the motors are a gem... but the body's are junk. Lol, I pick engine pieces off them all the time.

I just remembered (a little off topic) that the clutch master cylinder from the Tacoma also swaps over! I just had to swap the pedal input rod from the Supra over to the Tacoma clutch M/C, and also use long bolts to bolt it to the firewall (it only has 2 thru holes for mounting).

[82 Lover]

wait is this it?? cause im gonna buy it. but the port is not on the driver side. DAMMMMIT! please someone confirm

Nope, that's not it. That is for a Celica, not a Supra. There are a lot of parts on that page listed for a Supra, but they are only for a Celica. The oil pumps are a HUGE difference. Also, the oil pumps listed for the 5MGE are listed wrong, because there are differences in the body length due to the deeper oil pan of 85+. Rule of thumb for Ebay, always double check/triple check parts fitment by cross-referencing other catalogs and sites, and of course asking questions on here.
