Metric or standard box wrench bleeder nipples and what size front and rear if different size bleeders? Wifey Escape hence limited working time, original unit suddendly failed at 126K, vehicle being used several times daily. THX.....~~=o&o>...... Share this post Link to post Share on other sites
Knottynuts Report post Posted February 13 There's no rule especially if they've been replaced before. 8mm is the most common followed by 10mm but sometimes they're 3/8". Throw a socket over the bleeder and when you find the right size break it loose first and then use a wrench during the bleeding process. Share this post Link to post Share on other sites
