im trying to get the rear brakes off so i can replace them - there rusted pretty bad cause the car was sitting outside for 2years, any ideas on what to use on the bolts to get them off?

PB blaster works surprisingly well on rusted bolts. Buy a mini sledge and a rubber mallot also. A little bit of light tapping will ease the tension in there.

Heat the bolts up, spray em with pb blaster (be careful cuz every now and then it lights on fire) if that dont work use a small impact.

get your self a 6-point 14mm closed end wrench and a rubber mallot. soak it in wd-40 or equivalent then hold the wrench on with one hand and slam it with a malot in your other hand. you realy need the six point to keep from rounding them off. trust me its worth the $8 it will cost you at sears not to round those bolts off.

man those are some scummed up breaks it will be worth your while to go to a hardware store and buy some replacement caliper bolts. they are grade ten 14mm fine thread if they end up getting to rusted to tell from the ones you have. looks like you're looking at a rebuild on those calipers too. good luck

ooor, get a set of craftsman bolt-out's at sears. they really help with rusty/damaged nuts and bolts.


you can sorta se how they work.. they bite into the nut/bolt with sharp edges and they DON'T LET GO! unless of course you break the bolt head off...

thanks for all the suggestions - looks like im heading to sears for some pb blaster and a set of those bolt outs. as for rebuilding them i think ill pass and just buy oems from mazdatrix or the dealer :\

Ge them from mazdaformance instead or mazdacomp if your a member. Those two places will give you a discount over the dealer.
