I did a search as i know this was covered but i couldn't find anything, maybe it was my wording, anyways i upgraded my 92 dx brakes from rear drums to disc brakes. After bleeding the brakes several times the pedal feel is still soft. I came across some info outside of H-T which stated that a bigger master cylinder was needed to provide more fluid to the rear brakes. In addition to that he recommended a larger brake booster and proportioning valve. My question is, does this sound correct or a bit over kill and if so what master cylinder would be sufficent? Thanx in advance.

 

hes right. get a bigger master and bb and pv.

 

First off, ask him why you need a bigger brake master cylinder, and a larger brake booster? Post the answer here. You may have something going out, but you do not need that crap.

 

he said that the master cylinder isn't providing enough fluid for the newly added rear disk brakes. i also upgraded the front brakes to a gsr setup! some people say that i don't need one but others say otherwise.

the bigger piston of the master cylinder, the more panel effect, less psi.

you'll need the Proportional valve for sure but I am not sure about MC

 

get the prop valve for sure... i had GSR brakes on my Ek with stock MC/BB... BUT i did use a 99-00 Si prpo vavle...... brakes were just fine... I now have full 5 lug and ITR MC/BB, and now late braking Pwns me

Also.. check to make sure that your hydro lines arent expanding when you put pressure on them, over time they get weak

 

I 'm going to upgrade the MC but which prop valve should i get?

 

I have del sol rear disc conversion on my dx, I plan to upgrade the The rest sooner or later, but for now it is all still dx up at the pedals, and mine works just fine! It is recommended, but not mecessary to do the upgrade!
