hey guys I got a dumb question to ask is there a difference between the brakes on a 98 Honda Civic EX model and the DX model

 

ex model use a diff caliper, bracket and bigger rotor. I think a different spidle

 

I think you mean knuckle, not spindle.

 

Rear drums are the same. The front rotors are larger. Ex has a different prop valve whereas the rest DX, Si, etc all share the same 4040 prop valve

 

Wrong for 96-00. All share same prop valve. 92-95 have different ones

 

I have found reputable posters claim the Si/DX/HX are the same but only the EX is different because the bias on large front rotors+rear drum(Ex) is not the same as large front+rear disc(si) or small front rotors + rear drum (DX hx)
If that is wrong then I apologize.
