Hi, Be grateful for any advice. My BM has developed a leak at the brake booster end seal where there is fluid stain on the booster cover (Low reservoir warning light came on). What's best: try to get it refurbished (tried looking for replacement seals kit but no luck anywhere) or replace it with a salvaged one (but that will be equally old). My BM is a Tokico BM44 and car is 1990 S13 with ABS. Any suggestions appreciated.
