Brakes - 70/55

[frosty]

Would anyone know if you could bolt up  ST141 Corona  brakes to the ke70/55 strut to achieve 250mm discs?

thanks

Hi Mate !   Lots of details on here, if you go searching; regarding brake upgrades on the front of KE30/55/70 Rollas, as Rollas were never well known, for their "great braking ability"  I remember reading lots a threads, when I did my front end upgrade  years ago, which was a resounding success.  However, it involved replacing the whole strut, LCAs, & discs & calipers.  When I finished, I found I had to replace the brake master cylinder with a Mitsi Pajero one.  

I finished up with Corona struts, 3T Toyo adjustable top pivots, Cresida discs & calipers off to different model Cresidas; & the Pajero master cylinder. It was quite a journey, & I learnt a lot, but the end result, has proven to be reliable & trouble free.

Go back & look through my posts, & you'll find a lot of info there, along with a few pics.

cheers for the reply Banjo ~ I had had a search to no avail. I knew about replacing the whole strut, but my question was really about wether the ST141 corona brakes - backing plate, rotor and caliper ~ would actually just bolt to the existing strut.

Others may correct me; but I thing the simple answer is no.  It's over a decade ago now, since I did mine; but At least, I think I had to replace the top pivots, & they had to be adjustable to get the camber right. I know it was a good learning experience, & there was a lot of measurements taken, with the wheels & weight on a flat concrete floor.  Steering linkage lengths also came into play.  I'll have a read through my original thread tonight, & see if it brings back other memories of this exercise to light.  I do remember, I also fitted a much thicker anti-sway bar, which really helped, & some really good Koni shockers in the Corona strut tubes.

I seem to remember, there was a very popular conversion, called the "PUG" conversion, which used an early model Peugeot disc caliper off memory. 

I do remember, that you had to weld the lower spring support & retainer on, so that when the wheel was hanging free, that there was still some compression on the spring, at all times.
