need your help people

Good morning guys
I really need some help my 90 keeps eating rear inside pads in the last 6 mouths it has eating 3 set of pads I set of disks and had new callipers but still keeps eating them it has a disco rear axel on it. its not losing fluid I was not running mud dust shield but have put back on to see if it makes any defence at all. I live on a farm and has a very bad dirt road will that make any difference at all. I have tried 3 makes of pad 1. ferodo 2 mintex 3 and wait for it britpart hd pads that have lasted the longest by far but they are know getting down.
so if any one has any ideas plz tell me
many thanks nick

Do the pads wear unevenly at the back or the same together?

its the dirt making a grinding paste.

correct me if im wrong but these are twin pot rears? not floating calipers. If so i would be checking that the pistons are not seized and second that you dont have an air pocket or blockage to your outside piston. Sometimes you can end up with a crystal type of substance in the brake system when fluid has not been maintained. Find someone with a good brake bleeder, i always find the type that plugs onto your compressor line gives the best bleed.

One other thing that might be worth checking is that the brake discs you have fitted match the caliper. There are some differences in rear calipers for disco's so it may mean the caliper is not sitting central on the brake disc. This would be fairly evident by how far the piston sits on one side to the other

Yep would say its the pistons sticking, have the same problem on mine.
The inside pad is shot, I would take the calliper off, clean it up and fit new seals and piston.
Mine is off the road awaiting some sunshine so I can fit new discs and re furbished callipers.
Did you ever find rear pulling to one side under braking ?

Thanks for that guys only eating one pad on each on the inside calipers are new with in a year and free not stuck have a very very good bleeding kit so I know there is no air in there just stumped on what it could be

Could it be the master cylinder not allowing the pressure to bleed off when you take your foot off the pedal therefore causing the pads to drag on the disks?

It'll most likely be the lack of mud shields. I used to have the same problem when my 90 spent most of it's time driving muddy wet forest tracks. Would go through inside pads on the rear like nobody's business. Now I don't use it off road anywhere near as much and the abnormal wear has stopped.

Unfortunately if you do fit the mud shields it makes cleaning etc. after being off-road a bit of a pain. But that's your choice, it's that or changing the pads more often.
