I am rebuilding my rear brakes. I've taken everything apart, cleaned them with Simple Green and am currently soaking the parts in Evaporust. However, I might need to sandblast them.
1. Anything I should know before I proceed? 2. What to plug/tape up? I'm assuming all holes and machined surfaces? 3. What about the area in the caliper where the piston goes? 4. What blasting media should I use? I have some dull aluminum oxide I've used several times. I've looked on the 'Net and found a few tidbits, but nothing specific to 914 brake calipers, so I thought I'd post here and see if anyone had any experience, tips and advice. Thanks! |

Use glass beads not sand.

QUOTE(914Sixer @ Mar 12 2022, 05:17 AM)  Use glass beads not sand. Thanks! Will do! QUOTE(Shivers @ Mar 11 2022, 08:30 PM) Thanks! This was helpful, but there was only a brief mention of sandblasting. I have the PMB video bookmarked as well, so between this and that I should have what I need to rebuild these, but I'd still like to know what I need to do to properly sandblast these. |
