Hi guys.

As per topic, what models of Proton i can use and basically plug and play without custom made brackets? And do i need to replace the brake master pump?

Why i mentioned alternative models is because i am planning to use chop shop units and since Persona's rear disc set is harder to find so i am looking at alternative ones. I heard about using Neo, Waja and Gen 2's brake but unsure if its completely plug and play (without custom made brackets).

Gen.2/Neo rear disc are the same. Plug & play into Persona using back original trailing arm. Need to replace hand-brake cable.

First of all, thanks for the inputs.

I went back to my mech who modded my ex Myvi front brakes to Civic big brakes many years ago. He recommends Lancer rear brake set for my Persona. The rotors, caliper and parts are the same with Waja. So no issue with spares in the future. I was quoted RM750 for the set (used) plus labor RM120. If cable can't be reused, then need to replace and that will cost me RM70 per set. Since i drive fast a lot and i find that this car does not slow down fast enough on 2 disc, i think its a good choice to convert the rear drums to disc.

Mods coming soon....... smile_approve.gif

Bro., as FWD rely more on the front brake to stop, I would rather improve the front set to larger disc, or better/larger vacuum servo, and better brake pads. If not mistaken, it is like 80%/20% braking efficiency for front/rear, that is why the front normally have larger disc and ventilated.
My Mitsu have VR front disc (bigger then the original) and better biting pads, rear still the normal smaller disc and normal pads, but still the rears locks faster then the front.

OK. thanks for your inputs. I appreciate it.

Btw, reason for doing so is because i am so fed up of fixing the rear drums. And the handbrake on it does not work as well even after adjustment for many times. It's just not efficient at all. IMHO.

How did you adjust ? By open up drum or just adjust the cable near handbrake lever? At Lowyat got quite many people sell street performance pad,may be you can try slightly more aggresive pad for your front brake.

Actually for hand brakes, drums are better (more contact surface)
Yes, as mentioned by bro. eddievh handbrakes have to adjusted from inside first to shift the shoes as close to drum surface from one end. Pulling the hand brake cable activates the other end of the brake shoe.

I had handbrake problems with my rear disc too, and had to change the calipers twice before I solve this problem. Seems the auto adjustment was not working, so every few thousand km got to manually adjust...... smile_blackeye.gif
