For some reason the front breaks keep holding as I drive,but not all the time, I replaced the calipers but stil nothing, looking for some answers
My breaks keep holding on 1995 Volkswagen Golf
Bad brake lines, or kinked lines can cause this. You should clean the mating surfaces where the caliper will slide against the caliper mount. Do not use grease or any lubricant there. If you get it on the brakes, you will not be able to stop very well, and the oil will attract dirt and potentially make the problem worse.
