I am looking for a little bit better pedal feel and knowing that the SE has bigger brakes i am assuming the mstr cylinder is of a bigger bore than the 12as. is it a relitlvly easy swap what i mean by easy is would i have to bend new lines to fit? i have ss b lines and cross drilled and slotted rotors x 4. but i want to maybe get a bit bigger master cyl. without breaking the bank has anyone done this if so was it an improvment.

 

so nobody knows anything you cant be serious?

 

check with your local mazda dealer, they can pull up exploded diagrams and tell you for sure.

Ive been thinking of doing the same thing

 

Parts list that I checked say that all 84-85s with rear disc brakes use the same master, which implies the GSL-SE & GSL use the same for those years

 

I was having some brake issues a while back and removed the Brake MC from my GSL to compare to the SE they were the same Good Luck

 

excellent thats good news. does anyone know if the porportioning valves are the same gs, gsl and se?
