Mastercylinder swap -s10 blazer

im driving an s10 blazer with the stock 235's and an unwanted 4 inch suspension lift (i only drive this one on the street). im going to start towing my 87 suzuki - thats why i dont use the blazer. well anyway my brakes suck, once i start towing this thing it could get real bad fast. i know just about any mastercylinder from a chevy truck would work but im wondering what one should i use if any?

i was eyeing up a k5 blazers but if i go too big wont i lock up quickly? i dont want to be able to tap the brakes and lock all 4 up on the highway, i just want to be able to do that if i put them to the floor.

so what do you all think? 1/2 - or 3/4? i know 1tons are way too much for my stock tires

or should i go with some brake upgrades i dont want to spend more then 80 bucks on this so slotted rotors are out, any cheap pads that work good out there? i put tons of miles on so they have to last

and im useing a tow bar for the suzuki so i have no trailer brakes

I used a 94 four door s15 jimmy to tow my 86 s10 blazer with a solid towbar with no problems, and plenty of brakes.

The master cylinder isn't likely the cause of the weak brakes. I would bleed your brakes, have your rear drums turned, adjust the shoes, put on some good rotors and premium pads.

Old brown brake fluid also compresses alot more (=soft brakes) than fresh clear fluid. When you are bleeding, flush out all the old fluid if it has any discolouration to it.

A master cylinder from a 1/2 ton or 3/4 ton truck may supply an excessive amount of line pressure to your stock 1/4 ton brake components, which will expose any weak points in your brake system really quickly.

It may be worth while to sell the blazer and buy a vehicle more apt to towing, like at least a 1/2 ton truck. This would make going and stopping much easier on the vehicle on yourself.

So fare as upgrading the brakes, most pads will react the same to stock rotors. You can either upgrade them or do another brake upgrade, like a rear disk set up or something like that(more expensive then you want).

rear disks wouldnt cost me a thing.. my dad has a small machine shop and lots of welders. we did our 14bolt and used 10bolt parts

i think ill just adjust the rears a little more and change the fluid. i blead them about 3 months ago so i dont think its that. o well ill take it as i go
