Customers found the product to be of great quality, practicality, and usability, particularly for replacements on older model cars and universal retrofits. The price point was highly appreciated, with many noting it as a major benefit of the product. Some customers suggested including instructions for newcomers to this style of the caliper. A few customers mentioned minor inconsistencies but overall, it performed as expected. Compared to other options, this product stood out for its affordability and functionality.

Are these QTU calipers? I am running these with a wilwood tandem master cylinder and having problems getting correct pedal pressure. I was told around 1980 GM switched to QTU calipers (quick take up) calipers that require a different master cylinder. Wondering if these require a different master cylinder.... thx
