Is it possible to fit disc brakes to a 107E Prefect? I have seen the conversion kit by Milton Race for the 105E, but someone told me Milton were no longer going. Any suggestions?June 7, 2018 at 6:49 am #61799
Milton are definitely still around and going strong, so not sure where you heard that bit of misinformation! We’ve sold a fair few of their disc brake conversions for the 105E.
Someone else may be able to provide some input to the 107E, I assume then it’s not the same front strut/hub as the 105E, which is why the Milton option isn’t applicable?

Pretty sure the strut is different on the backplate mount holes.

The mounting holes for the brake backplates do not align with a bracket for the 105E, as Ken states. They aren’t sufficiently displaced to allow welding and drilling. Also, if you fit 105E-ish hubs to the front, you have a stud spacing of 4.25″ p.c.d. so you’d need to do something to the rear, which would remain at 5.5″, or run two different wheel types.June 7, 2018 at 6:58 pm #61805
Thanks for this. Looks like it will be harder than I thought. Is there an alternative strut/hub arrangement that might fit on a 107E, or will I have to make some kind of compromise? My old drum brakes just aren’t sharp enough for when idiots pull out directly in front of me.June 8, 2018 at 3:42 pm #61807
None that I know of. The old way was to fit Classic / Capri struts, but these also need the appropriate track control arms, giving a wider track and negative camber. You still have the issue of the wheel stud spacing. Actually, I’ve always found the 107E brakes more than adequate: the MoT tester always commented on the exceptionally high readings. The big advantage of disc brakes is the reduction of fade rather than greater efficiency.
Everything needs to be working as designed, though.June 8, 2018 at 5:19 pm #61808
Thanks. I will abandon the disc brakes idea and focus on making the drum brakes as good as they can be. At least I get to keep the original bits on it!December 26, 2018 at 6:26 am #63436
Would there be any issues with putting a vacuum booster on it?. That is what I did with my 105e back in 1969 (Too long ago to contemplate!!), it worked a treat.
Disc brakes would have been the better option with a lairy 1340cc’s upfront sporting 40mm sidedraft Strombergs and a manifold.
Hope this helps. IanDecember 26, 2018 at 8:22 am #63438
