Front Disk Brakes Conversion

Hi Guys
I bought a front disk brakes conversion kit for my BN6.
It comes from Betaset, but it's very close to the one from AH Spares. Some of the components are clearly coming from AH Spares.
Unfortunately, the kit was delivered w/o instruction.
Before starting the job, I thought maybe some of you guys could share experiences with installation of such conversion kit on an AH, or some tricks to get it right the first time and avoid typical mistakes?
Any good trick will help!
Thanks in advance and have good time with your Healey! :smile:
Cheers
Patrick
 
That does look just like the AH Spares kit. I installed the Denis Welch kit on my BN4 several years ago, and couple of thoughts:
The kit shows new hubs and bearings. To get the bearings properly installed, you will need shims to get them rotating freely with no end-play. You should have an assortment of spacer shims on hand. Lubricate the bearings with oil while you test the shims. When you get close, but still loose, if you have a dial indicator, you can measure the end play and calculate the proper thickness of the shim pack. Once you get that right, bolt the disc to the back of the hub, and measure the amount of wobble in the disc. The limit is 0.004". You will have to make sure the bolting faces of the hub and disc are completely clean. After that's done, you grease the bearings.

It will look better if you paint the rough part of the discs with caliper paint so they don't look rusty through the wheel spokes.

If it's like mine, the solid brake lines need to make a tight loop between the "L" bracket and the caliper. To make that loop without kinking the tubing requires a tube bender that does small radii. I make one using flat washers, The other thing I recommend it get Speed Bleeders to make bleeding easier.
 
I installed the AH Spares kit in my BN2 100M. The only issue I ran into was that the bolts holding the calipers on were too long and contacted the rotor. I had to grind them down to avoid.
 
great thanks to both of you for sharing your advices and your experience !
one more question about grease, any special type or brand to grease the bearings ?
