on my 99 4runner my rear right brake is locking up, only when its cold thought... it doesnt happen in reverse but when i put it in drive and hit the gas its ok unless i push the brake and i can feel it catch. i replaced the wheel cylinder yesterday and thought i had it fixed until after i changed the oil today and backed out of the driveway. when in drive if i press the brake from a roll it really grabs and it will will stay unless i give it some gas. after i drive it about a 1/4 mile its fine but you can still feel it grabbing harder than the left rear. any ideas?

 

is the axle brake line kinked any on the right side cuz I had the same prob on my 88 Subaru and it was just a kind in the hard line?

 

have you inspected the drum for brake dust gumming up? have you made sure your axle seals are not leaking?

 

i checked averything out when i replaced the wheel cylinder and i didnt see any kinks.. when i bled the line everything seemed fine. when i pulled the drum off it wasnt gummy or anything it looked like there was some small metal shaving but not very much at all. there was a little bit of rust inside but everything seemed to move ok. the only other thing that im wondering is the e-brake has never worked since we bought it.. if you pull it really hard it seems so work a little but it wont keep the truck from moving..
