Mart's Real Hot Rods 

Mart's Project Pop!
Part 6: Disc brakes the easy way. 
(I hope)
 
Ok. This is whatr we want to get rid of. Enfo's version of the wide five bolt pattern, plus mechanical brakes.Backing plate already removed before shot was taken. 
These were the initial candidates. From left, Ford Cortina: Right stud pattern, wrong bearings, bearings too far apart, plus wheel mounting face relatively far outboard, loading the outer bearing. Centre: Alfa; Bearings a more reasonable distance apart, but bigger. could be sleeved. bad stud pattern, though. Plus Minx wheel fouled the caliper. Right: Ford P100 pickup. Wrong bearings, too far apart, right stud pattern for taxi steels, Almost tried to use this, but settled for another option:......

Anglia drums. Well, almost. Forget the drum, it's the hub I'm interested in. Outer bearing same as Pop. Inner bearing different on Anglia, but Pop bearing is same series, and is a direct swap. Uses same bolt pattern as the Minx steels I have. also note the wheel mounting face is a good inch behind the outer bearing, easier on the bearings.

Here's the Anglia hub separated from the drum. Studs were pressed out, the outer diameter trued in the lathe. Studs replaced with 100E studs.

Od of hub was skimmed down to fit inside this Ford Sierra front disc. Cheap and commonly available, it's the modern type that fits over the front of the hub. Bolt pattern matches. Spigot diameter not quite right, has very slight clearance. Studs could do with being slightly longer, will look out for something suitable. Shape of disc, the cylindrical section between the flange and the disc, dictates the use of modern type calipers. 
Here's the view from the rear with a wheel bolted in place. Alfa caliper in background does not fit, will source some Sierra calipers from the scrapyard. Should be plenty of clearance, as Sierra's use 13" wheels. 
Caliper bought from local breakers, is a snug fit on rear side of spindle, clears steering arm ok, though. Patterns for brackets cut from a cerial packet. Caliper is not as big as the photo would suggest. 
Caliper was stripped down (easy, no tools required) to ensure correct alignment between pad and disc. Once cardboard patterns were completed, design was transferred to 8mm steel plate. 
Plates are spaced off the spindle, washers used to get the correct dimension. Top plate had to be trimmed to clear the top of the kingpin. Bottom plate not finished yet, wanted to make sure it was going to work before doing all that filing. Slight cock-up, there's not enough clearance between that bolt and the lower grease nipple. Plate for other side will be tapped, so no nut needed. Might heli-coil this one, or just make another plate (dammit). Caliper does not interfere with fitting/removal of track rod ends.

Not the prettiest steel wheel around, but believe it or not, Hillman Minx steels are the only 15" steel wheel that fit Ford 4.25" stud pattern. There may be others, (Alfa, maybe?) but try finding them. Preliminary plan was to shod these with 5.60:15's off a VW beetle, but I also picked up a pair of 155:15's, 'cos I think I'd rather run radials instead. Have been checking tyre sizes and am leaning towards a pair Avon of 215/75/15's for the back. These are almost 28" tall, and 8.5" wide, should be more than enough for the little Pop with stock arches. Even with these, it will probably necessitate narrowing the frame and modifying the inner wheelarches. 
PS to above, I've decided to keep the Minx steels and crossplies.

Will update this page when the job progresses.
