My 90s brakes were terrible , the pedal was hard with no feel in them at all

They got to a point then no matter how hard you pressed they didn't get any better, totally impossible to lock the wheels up

The servo is working with no leaks

The garage though it might be the shuttle valve, it's a 300tdi pre abs

The valve was replaced and they're definitely better but still not great

A previous owner fitted green stuff pads which I told are great when hot but ****e when cold which is most of the time

So my next step is to change the pads but what to, I don't want to replace them with ones that'll be as bad

Any suggestions

Have got the same issue with my 90 300tdi was going to change the servo. I would be interested to no if changing the pads solves this
 
Ferodo Premier pads are a good option. Don't entertain their SL range though...
 
+1 for Mintex
Cheap, effective and long lasting - the previous rear pads on my 90 lasted 1500 miles ....

....first 4 letters were 'Brit'
 
Thanks for that, looks like mintex is the one to go for

My brakes had no feel, the pedal went hard and no matter how much I pressed they didn't stop me any quicker

How it was explained to me is the shuttle valve splits the braking force up and directs it to each wheel , if one wheel is off the ground it diverts the force to the other 3 wheels

This valve was seized so the pedal felt normal to a point , that point was when the fluid reached the siezed valve which was only letting some of it reach the brakes

Changing this valve bought feel back to the pedal , they definitely improved but still not as good as I think they should be which is why I'm looking at the pads

I have run both mintex (road compound pad i forget the number) and ferodo premiers not much to choose between them I found the mintex were slightly more prone to squealing but both excellent pads for road use....
 
Might be an idea to service the callipers when you change the pads - make sure that the pistons and seals aren't damaged and move in and out of the caliper body easily under brake pedal pressure - don't forget to copper grease the back of the pads to prevent brake squeal ;)
 
Thanks for the advice but I won't be doing it, the brakes are bad enough as it is , I'll get him to check the calipers though

When I bought it the previous owner fitted new discs , he'd had them a while , one had a bit of a warp in it so he bought 2 new ones but only replaced the warped one

As he'd had them a while they were different makes but he did give me the unused disc

That wouldn't affect them would it ?
 
Odd thickness discs i.e. one new, one worn would cause a slight pull to one side as it slightly changes the piston area between the callipers.
in theory two diferent makes of disc shouldnt make much much difference so long as they are both identical thickness and material.... For the cost just replace the discs with a matched pair at the smae time as the pads it eliminates any possibility of a problem then (mintex sell a 'brake box' with discs and pads in)
