1968 Ford XL Disc Brake System Overhaul : part 3 Rotor and Piston
2023, November 14
part 1 - part 2 - part 3 - part 4 - part 5 - part 6 - part 7 - part 8I had a complete spare set of these front disc brakes so before I took the XL apart I had all this already prepped.
New bearings and races.
Brand new rotors. These are the 1968 year only rotor deal and as you can see a two piece design. My biggest fear on these is they are becoming hard to find. In fact I cleaned Rock Auto out. Since we have two cars now with these 1968 front disc brakes on them. A couple years ago Rock Auto had two brands of these in stock. What's interesting is when I bought the Raybestos out (they only had 2 left) I noticed the AC Delco brand they used to sell wasn't even listed. I thought that odd. I looked up the AC Delco part number then did a part number search in Rock Auto on that AC Delco and sure enough they showed 4 in stock at a really low price, but someone at Rock Auto didn't have the part number linked to an application anymore, so they were sitting in limbo. I took a chance and bought all 4 and sure enough they showed up. Sometimes it pays to think out of the box.
With the economy, such that it is currently, I just bought a lifetime supply of disc brakes for these cars; rotors, calipers, caliper parts, hoses, hardware and pads.
New wheel studs
It presses together very similar to a 4 wheel drive pickup rotor. It's just a smaller version of the 1 ton brakes on our old Dodge Power Wagon.
That's both rotors done.
The calipers I cleaned and powder coated and they just received all new internals. These calipers didn't have the amount of rust in them as the golden XL did. These brakes are off my other '68 XL. I use the Red Rubber Grease as you do not want to use petroleum based lube on the seals. This grease is vegetable based and will not cause the seals to expand.
The old pistons were still pitted though and needed to go.
For the brake line bolt, these were the closest I could find.
These are a wee bit too long as you can see the original one on the right compared to the old one in the middle. I just shortened them a smidge.
Both calipers put together.
