![]() ![]() It wasn't difficult, got it on the first try. I cut the bracket enough to fit behind the spindle, then traced where it needed to be trimmed. I made the first caliper bracket mainly both brackets by trial and error. Still working on solutions, when I do I'll post the pics of the progress. That pic of the pads was the last pic I was able to upload. On top are the CPP oversize metric pads, the bottom are D614 pads, which fit the GM D52 calipers: I have a pic that shows the difference in pads. The new owner isn't sure which way he wants to go, but there's plenty of time for that. The usual other costs involved include new lines, which I already bought before I sold the car, and a new MC and booster. On the other hand, he thinks the new owner was crazy to have passed on the '65-'66 conversion I was preparing to install. My brake guy says these pads will provide much better heat transfer than the CPP pads. Plus, the piston in the big caliper is 3/16" larger than the big bore metrics, and the pads are MUCH bigger than the oversize pads supplied with CPP calipers, and 1/16" thicker. $212 more than the Granada/S10 conversion, but about half is offset by not having to buy new wheels. ![]() New calipers are $130, and the pads are another $44. Timken bearings and seals, hoses, prop valve, and hardware, is estimated at another $175. $102 saved, and I get to cut stuff up.Įstimated cost of rotors is $120, quality is mid-range. It looked real easy to modify weld-on metrics for the plate that bolts to the outside of the spindle. There was a pair of weld-on rear big GM brackets that aren't cut too deep for $29 on ebay. A 1' length of 3/4" OD x 3/8" ID tube for spacers, was $5. A friend with a machine shop widened the opening to 1.249", and ground the bases down to 7/16" for $30. I got spacers for early Ford spindles for $43. Then it would have been just a matter of fabricating brackets for the larger calipers. ![]() We were all set to get a conversion that supplied only the spacers and ACC type caliper brackets for $220 on Ebay. By using washers under a Mustang rotor, we determined that the spindle spacer should be 7/16" thick if a 1/16" thick thrust washer is used, or 3/8" for a 1/8" thick washer. One thing we noticed, was that having enough room for the cotter pin was an issue, both in the PDF, and earlier posts by other members. The CPP calipers needed to be ground down about 3/32", something the new owner and I didn't want to do. The pads are much larger than the ones supplied with the big bore metrics from CPP, and the bigger calipers have sufficient clearance with 14" wheels. However, we're going to use the calipers for full size GM's, and D614 police package pads. We carry all the brake hydraulics and friction components you need for a complete repair.Thanks to the PDF posted by Allan, Dave and Tom, we're going ahead with a conversion that uses a plate to attach the caliper bracket, ala the ACC conversion, and '68-'72 Mustang rotors that are used with various other conversions. If you need a new brake caliper or other brake components, including brake pads, brake caliper guide pins, or brake rotors, visit O'Reilly Parts. If the caliper is leaking, or if the piston is stuck or noticeably damaged, the brake caliper should be replaced to ensure you can continue to drive and brake safely. It is important to always inspect the brake calipers, as well as the brake caliper bracket and guide pins, when you perform brake pad and rotor service. If the caliper is leaking and enough brake fluid leaks from the piston seal, your brakes may even stop working entirely. If only one brake caliper is sticking, this may cause your vehicle to pull to one side, squeal, or make rubbing noises when braking. This can cause your brake pads to be in constant contact with the rotor and may result in uneven or premature brake pad or rotor wear. Over time, brake calipers may develop leaks from the piston seal, or the piston inside the caliper may stick. Brake calipers use fluid pressure from the brake master cylinder to compress the brake pads against the rotor surface and maintain the friction necessary to stop your vehicle. The brake caliper is a hydraulic component in the disc brake system, and is made up of the caliper body, a brake caliper piston and seal, and a bleeder valve to allow the brakes to be bled. ![]()
