300 tdi brakes binding

hi all.any ideas what can be making the rear brakes on my 97 disco bind and heat up?as im driving i can feel them dragging and the pedal gets tight as if the system is preasurising.i repalced both rear calipers today but still the problem remains.

hi sounds like your caliper pistons are siezed. you have i believe 3 options.1 you can excercise the pistons.[remove one of the pads and pump the brake pedal once then push that piston back in then do the same to the opposite pad]option2 change the seals and pistons option 3 buy a new caliper.

sorry mate ignore my comments above. it could be a problem with the seals in the brake master cylinder or the slave cylinder as you are applying the brakes when you release them the pads are not returning.

thanks for that.i just been out in it and i noticed that a front brake is squeiking so i suppose that could be sticking and heating the system causing it to preasurise.will have to have another look in the morning

either that,or it is indeed the master cylinder/servo unit.these fail and cause alll sorts of problems!

just to update.i changed the master cylinder and it seems to be sorted.thanks for the help

Clever bunch us landy owners
