looking for info on master cylinder upgrades. I know about the 1" master cylinders that AllPro and Marlin sell (which is a '93-'94 Landcruiser non-ABS master - stock is a 13/16" bore). Basically I'm looking for a firmer pedal, I replaced my master cyl about 2 years ago, so that's not my problem and I bleed/change the fluid out once a year. Does anyone know what other master cylinders will fit the 4 post mount on the brake booster? Links? I've been looking around the other sites and can't really find any interchange info. I've heard early 90's 4runners also had a 1" bore, but that there was also a 15/16" bore available somewhere.
I am planning on swapping on a set of T100 "finned" calipers in the near future with the same size pistons (vs. one smaller piston/one larger piston on the stock calipers), so I really want the larger master cyl volume before I do that.
I did find this thread - and I'm hoping 4runnerChevy can remember what year Supra the 15/16" bore came out of
If I can find some good info, I'll put together a write-up with the different options and sizes available.Originally Posted by 4runnerchevy
