Gen7 Brake Overhaul/upgrade

[JonnyA]

Hi!

I've had my gen 7 celica 140 for about 8 months now and love it!

Having changed car I obviously knew the feel of everything would change, pedals etc. Recently i've been able to take my hands off the wheel and allow my sister to drive it when she was home just to see what it was like and she commented on the brake pedal feeling soft. Another person said the same. Bearing this in mind, i have started compairing to any other car/van i drive and it does feel a bit on the soft side so i've decided to give its braking system a good overhaul!

I'm sure that simply bleeding the system could probably cure most of this problem, or replacing the brake fluid altogether.

However, having upgraded brakes on my last car with ebc grooved discs/greenstuff pads combo and felt the difference, i'd like to maybe change the discs and possibly calipers. I have researched into it a bit and to my current knowledge my pre-facelift celica has 255mm diameter discs and the facelift 140/190 have 275mm on the front and the rear discs are common to both 140/190 pre and post facelift?

I then thought that it would be good to get a set of larger discs and calipers from the facelift 140 or 190 as a direct replacement and i am wondering if everthing else regarding the braking system is the same i.e. mounting points for caliper and master brake cylinder, so that it will operate as intended and not mess it up! I thought about changing the fronts to larger discs may upset the brake balance aswell but surely if that happened on the facelift anyway it wont be a problem?

If it is a straight swap then i think ill get on the phone to the breakers for calipers and get some new grooved discs and ebc redstuff pads and some dot5.1 fluid and if i've got cash left i might get some steel braided brake hoses as that will sharpen everything up that bit more!

In my search on the topic i came across this article that uses the existing calipers mounted further out and larger discs. However i think the company that made them (AEM) no longer produce them, or have shutdown altogether! I must admit, they certainly do look the part in the last pic at the bottom!

AEM big brake upgrade

I'll stop ranting on now! Thanks alot!
