Greetings All, The subject of Disc Brake Mod's to the 500 has been covered multiple numbers of times on the forum, but I thought I would cover what has been done to my car
I have been greasing the front legs today and decided to investigate the slightly 'different' mod to my brakes while the wheels are off, I have also noticed that the dual grease nipples on the nearside leg are on the rear side and the offside leg has them on the front?? No idea why
The first pic shows the complete brake and caliper, the eagle eyes will notice that the outside of the caliper housing has been ground away and I assume that this is for wheel proximity clearance.
I have determined that the Caliper at least is a fiat item by part number and belongs to the 124,128,131,X1/9 family. This is a single piston sliding caliper with the piston being 48mm. The second pic shows two spacers fitted of 4.7mm each, likewise on the other side (wheel location?). Removal of the caliper and pads is simple. Pic three shows the Brake carrier, this is bolted to an adaptor plate that uses the bolt locations for a drum brake back plate. The last pic shows the adaptor plate and a late 126 (77-on) hub. The brake disc is only 200mm in diameter which is perplexing because the family size used is normally 227mm Any ideas folks?? I have found that the nearside disc is very slightly warped and causes a little squeak when the brakes are applied at low speed, not yet decided if I can live with it or go for an upgrade including braided steel pipes. I have added a pic of the brake caliper too.
I'll continue with the pipe change later.
