Its a rear big brake kit Jim, but not as you know it!

A tidy up today..catalogued all the parts used in development …here’s a pile of prototype parts..IMG_3895.jpeg
 
So today I took off the rear prototype BBK parts and carefully inspected them for any signs of failure / distress…

All’s well..smothered everything in blue loctite when assembled after an initial loosening of a bolt ..boy it makes it hard work to undo..even after you’ve cracked the nut..

You can see how the Nordlock hardened steel lock washers bite even to the steel bracket..

Very pleased to see that the pad sweep is perfect and the combo of Ferodo DS2500 pads and F01 7 series 370mm disc are all good.

So about 5,000 miles and all well…

Just finishing off painting the production version of the brackets prior to fitting those.IMG_0806.jpegIMG_0805.jpegIMG_0804.jpegIMG_0803.jpeg
 
Another couple of hours spent fettling rear brakes….cleaned the rear calipers and put some etch primer on the caliper cradles…bolted up the satin black painted BBK adapter brackets..with blue loctite and funky Swedish lock washers ..IMG_0815.jpegIMG_0814.jpegIMG_0816.jpeg
 
So I’ve done a photo sequence showing a neat way of determining, then doing, then checking the caliper carrier cradle machining required to use the F10 carrier cradles with the 370mm rear BBK adaptors…
first trial fit bracket to cradle,
second attempt to insert bolt in middle hole..it will just foul the carrier,
third mark said position of fouling,
fourth disassemble and machine small amount of metal away at said point,
fifth reassemble insert bolt and ideally 24mm washer…this will give the required cut area,
sixth disassemble and machine away required metal periodically checking to not go far..
finally reassemble and check clearance by using a 24mm socket ….simplesIMG_1273.JPGIMG_1272.JPGIMG_1271.JPGIMG_1270.JPGIMG_1269.JPGIMG_1268.JPGIMG_1267.JPGIMG_1266.JPGIMG_1265.JPGIMG_1264.JPGIMG_1263.JPG
