What is involved in switching to rear disc brakes on a 95 Escort Wagon? I
can get parts (heck the whole back-end) off an Escort GT pretty cheap so
price really isn't an issue. While I'm at it, whats the appropriate year
In case you are wondering, my brakes seem weak. The pedal pressure is
fine, it doesn't feel especially spongy, but especially when going down
hill you easily run out of brakes even with your foot all the way down. I
replaced the front pads a while ago with nice ceramic pads and it seemed
to improve the situation, but its back to being as crappy as ever now
(after 1 year) and I can't imagine its a problem in the front any more.
Also, are there any good diagnostic tools available for this car
(considering that its pre-OBD2), my fuel economy seems to be down around
30 mpg, which seems lower than it should be and I wanted to try to check
if the O2 sensor is working properly.
The standard brakes should perform adequately during normal driving
conditions if everything is functioning as it should. Either your
expectations are too high or there is a problem you've
overlooked. It could be a lot of things. Leaky caliper or wheel cylinder,
bad brake booster, etc.
For mixed driving, 30 mpg is good. EEC can only detect specific, obvious
problems with an O2 sensor. If it's just "slightly off" then no code is
I'm not sure what the definition of "adequate" is. The car stops, but
I've measured the decelleration on this car (a while ago) versus my 1990
Jetta. The Jetta could stop literally 50% faster (i.e. 50% more
decelleration). After changing the front pads it seemed to get better
(though still wasn't comparable to the Jetta) now its back to where it was
before, approximately. Interestingly, the Jetta is about the same weight
and the brake rotors are actually slightly smaller (10.25" on the Escort,
versus 10.1" on the Jetta... The Jetta does have rear discs though.
I can't imagine its a leaky caliper or wheel cylinder because I'm not
losing fluid. I suppose a caliper could be sticking, but that doesn't
seem plausible either because if that were the case I'd expect the braking
to be uneven, which it isn't. Also, it was my understanding that a faulty
brake booster pretty much universally causes the pedal effort to increase
but doesn't otherwise impact the braking. My pedal feel is actually
pretty good in the Escort (better than the Jetta) it just can't stop well.
So any idea whats involved in swapping in the GT's rear disc brakes?
Mixed means mostly highway and rural, not much "city" driving. My father
(who used to own the car) claimed to get 40 mpg in similar driving. I'm
not expecting to get the same gas mileage because he drives it more gently
than me, and I figure I get worse mileage in the winter since I think we
use oxygenated gasoline here, but I would figure I should be getting maybe
33-35 mpg. I was thinking perhaps a slightly contaminated MAF or oxygen
sensor which might be reading slowly or slightly off. Perhaps brake
cleaner (at least on the MAF sensor)...
The brake lines haven't been bled (possibly ever). It was my understanding
that brake bleeding would improve the "feel" of pedal, and the pedal doesn't
feel that bad (my Jetta for instance feels much worse despite having much
better braking). I have been scared of bleeding it because I have had very
mixed results in the past when trying to bleed (using a variety of different
Brake bleeding can get pretty messy, but most shops have power bleeders
and the service is pretty cheap. Just shoot a little penetrating oil
on the bleeder valves before you bring the car in.
I don't know, you're comparing German engineering to Ford engineering,
might be apples and oranges.
