Front disc brake problem
I have a 72 Blazer front Dana 44. I can’t mount the calipers because the pads seem too thick. I bought rebuilt calipers that look just like the old ones. The piston is retracted as far as possible. Rotors have no wear that I can see.
Are there different widths of calipers or rotors that I may have mixed up? The pads are the same thickness as the old ones ,but are at least 3/32” too thick per pad. I didn’t take it apart, so I don’t know if it ever fit. |
Re: Front disc brake problem
I just replaced my calipers with rebuilt from O'Reilly. My rotors are roughly 1.30" thick and the space from the inner surface of the caliper to the face of the piston is roughly 2.45". I have new pads on them and the piston sticks out of the caliper housing about 1/8" with everything assembled.

I don't know if there were different ones. I know it's shocking, but I have had O'Reilly's give me the wrong parts in the past...
I'll pull one of them apart tomorrow and get exact measurements if you want them. |

Re: Front disc brake problem
OK, but let me know. The wheels aren't on it yet and I would just need to pull one bolt to get more precise measurements.
Edit: I took one apart this morning because I wanted to be sure I didn't give you bad info. With the piston depressed, the inside measurement of the caliper is 2.50. The rotor measures 1.30 and the pads (new pads) measure 0.675, including the backing plate. I looked for my receipt but I couldn't find it. |

Another update...so I have been working with the passenger side caliper. I get the driver side out and it measures 2.5” like yours and fits just fine ...they look the same both are Delco calipers. So I guess I’ll have to go to the store and measure a few. Thanks for your help Truckster 👍🏼

You're very welcome. Sometimes the rebuilders put the wrong part in a box.
