Brembo Medium Brake Upgrade
The E1 wheels look great on a 240 but a rusty caliper behind it is so 1980's. I came across a set of the Brembo calipers needed for Bens medium brake upgrade so I decided to add them to the car.
Below is what I was working with and the rotors where already warped so that annoying peddle / wheel pulsing during hard braking gets old pretty fast.
I decided to use the the 316 mm rotor option as I was able to source the rotors and pads for essentially free and the modification required to the brake caliper was next to nothing.
My mock up showed where there would be contact between the caliper and the wheel spindle
Slight trimming with a Dremel is all it took
For the rim to clear the brake caliper I would need to run some wheel spacers. I ended up using 20 mm spacers but I suspect 15 mm would also work.
To do this I needed to press out the old studs from the wheel hub and I trimmed my extended studs as the lug nuts I use are capped.
Here's a comparison between the stock diameter rotor an my new 316 mm rotor
And the end result!
The fit behind the wheel was great
After a few hard burnish cycles I found the initial brake bite is better and I was fully confident hard braking into corners once I got use to the slight increase in front brake bias.
Some things I came across were;
Stock dust shields will need to be trimmed to accommodate the larger caliper if you desire to use them. The offset of the 316 mm rotor is not the same as the stock rotor which will allow you use the dust shield without and interference between the rotor and the dust shield.
I replaced my front wheel bearings when I had the hub out because they where 40 years old and replacing them is cheap and easy.
I used the brake line kit Ben sells. Works flawlessly and comes with the brake junction block port plugs you will need.
Patiently waiting for a rear brake solution will be next on your mod list.
