Hi,

My sister has a 95 wrx but she is always complaining about the brakes on it and to be honest compared to modern cars she has a point. It's got 4 pots on the front, 2 pots on the rear with braided hoses all round and it's also had the master cylinder changed for the larger one but the feel and bite is still poor.

Her husband (Swisstony) had a 2000 uk turbo and she is forever comparing the feel of his brakes to hers and we can't work out why her brakes are worse because he had single pot rears plus everything except the hard lines and servo on hers has been changed!

Did Subaru increase the servo assistance on the later models? Do servo's go weak? We know the servo is working but don't know to what degree

Thanks,

Paul

Her yes, me no The brakes completely lack bite, press the pedal and they work but they do feel wooden and she has now lost interest in the car I want it fixed so she'll fall in love with it again.

Brakes need an overhaul? Pistons in the 4pots tend to stick over time and need rebuilding.

Something aint right as my new one stops good with just 2 pot fronts and 2 pot rears ? standard lines and no doubt cheap fluid. What about trying one of those CDF brake stoppers ?

I forgot to mention that she's had 2 sets of 4 pots to try and cure this and the pistons are nice and free on her front brakes, one of the rears has seized but that shouldn't make this much difference.

That's been suggested thanks mate but sadly she is fed up with throwing money at the car and refuses to spend anymore money on it unless it can really be fixed

We all suspect servo but the servo works, by that I mean if you pump the pedal up hard with the engine off and start the engine with your foot on the brakes the pedal does drop

For example my 555 when I bought it had standard brakes all round and it was better! They are crap now but I know the reason why

Have you ever had the fluid changed with a machine rather than pump and nip ? Could be a damaged or blocked hard line somewhere ? Has it got ABS ?

Paulo P

Fluid has been changed many times but it's always been bled by hand. A blocked line isn't likely I wouldn't have thought but anything is possible now!

There is no ABS on her car, something else she hates

have you tried a more standard type pad like the standard genuine subaru ones which do not need as much heat in them to bite better?

Until a couple of months ago she had standard Subaru P1 pads, she now has EBC red stuff.

mine are crap to on my type r to. thinking of going brembos now ?

red stuff are uprated though, ebc green are the equiv. standard, but if you've had the standard pads & your not happy then its a no go!

all i can say is get saving for 6 or 8 pots if your not happy! I have only 2 pots on the front but had a full overhaul with s/steel pistons etc from godspeed & yes you need to use force on the peddle, unlike my mrs clio where you just touch it & your headbutting the steering wheel but even though 2 pots they are very good for me especially with his discs & pads i have too.
But that is how i have found the impreza's ive driven on 2 pots - i know you have 4 pots which are supposed to be better than 2's but you seem to be struggling for some mad reason!?

have you tried it on one of them brake tester machines where it looks at how it pulls up etc & see if that can point anything out.

Also what DOT fluids you tried?

I've told her to get some Brembo's if she's not happy but she refuses to spend any more cash on the car I think she is too used to over servo'd cars and simply won't press the pedal hard enough and that's what made me wonder if the later classic servos were more efficient.

It's on dot 5.1 fluid and has been for a couple of years.

tbh why worry too much about what can be done to change anything for the better if she refuses to spend any more money on it. If its not good enough then maybe she should move on to a more suitable car. Like a Fiesta or a Micra. Something that you wouldn't need to have sharp breaks on as it wouldn't go fast enough to worry about them

It's not an unprotected turbo boiling the **** off the brake fluid is it ?

coz if it was a simple cheap fix like fittin a later servo she would do it but prob dont wanna pay another 500 on brembos

Brake stopper made a difference on my car Paul, would be a doddle to fit on Zoe's.
