Brake master and booster info

[JamesDean91]

Okay my master is leaking and I think it's a 1" bore. I plan on doing tundra fronts and finally doing the rear brakes before a wheeling trip coming up.. My question is I've seen the GM 1ton master and the t100 I don't remember the bore on either and what was involved. If anyone has input on what one is worth the upgrade that would be awesome.. Also read about dual vs single diaphragm booster. What one should I use?

you should already have a dual diaphragm booster from the factory. It is an upgrade for the first gen guys but not 3rd gen and unless your are also doing a rear disk brake conversion just replace with a stock unit. there is plenty of volume in the stock MC for the TBU. A larger MC if used in in the way I think your going to, will create a super hard peddle. my 2 c's
