have a 1988 blazer put on new rear brake lines. now i need to bleed them. does anybody know the size of wrench fits the bleed screw ? hope it's not a special tool.

 

8MM six point works for my rears, and 10MM six point on the front. If you are using a twelve point it will round them off. You should buy a bleeder wrench from the tool aisle, it will be 8 on one end, and 10 on the other. Its also bent to keep your hand out of the way so you can see the fluid coming out. Sequence is RR, LR, RF, LF and yes you have to do all 4 of you had the rear only apart.

If you have already ruined them with the wrong wrench, then just get new bleeder **** at the parts store and put the new ones on instead.

 

thank"s so much for that info exspecialy using the six point socket. if i have any more questions i"ll be back so for know i"ll be closing this post now . thank you
