Hello everybody!
My Car: Honda Civic 1993 EX Sedan with ABS.
My brake pedal went till the floor yesterday. The brake was less efficient and than I pressed again 2 times and the brake back to normal and the pedal was harder again (harder, I mean at the normal pression).
This happened 2 times yesterday (with some time between them).
I phoned to a mechanic and he told me that I should change the master cylinder of the brake.
If the problem is the master cylinder, does the break fluid goes a little down?
I mean: Should the fluid level goes a bit down if the problem is only the master cylinder?
If the fluid level goes down, than is there some leak and that's the problem of pedal fading to the floor and not the M.C. ?
Or with the master cylinder broken can I have the fading on the pedal and the leak in the system?
I noticed my brake fluid is a little down comparing as it was before. But it's upper from the MIN level. Almost at MAX, but a bit down.
I though in changing some "repairs" (like rings) I dont know the name in English.
Is it possible? I don't know very well about the Master Cylinder. Only how it works. I mean the physical principles.
I know that the "repairs" aren't expensive.
So what do you think that it could be the problem?
THe master cylinder for this car here in my country is about US$ 500,00 new and outside Honda. At Honda it's US$ 750,00.
That's TOO MUCH money here !!! In local money it's R$ 1000,00 outside Honda and R$ 1500,00 at Honda.
Is it dangerous driving the car before solving the problem?
Thank You Guys.

Just checked Rodrigo,
This part is #13040023 by Centric and sells for $80.70US and can be shipped from the store mentioned! That's more what I expected and that is a wholesale price but you don't need to be a business to get it for that here!

Just so you can get an idea for shipping costs from the US - I just did and a 5 pound box from Massachusetts (example zip code = 01749) to anywhere in Brazil came to $32 for 6 to 10 days and $49 for a guarentee of not more than 10 days. You can calculate that too using www.usps.com .. Other shippers might be cheaper or faster. That was the US Postal Service.
I know you can't wait especially for something so important as brakes. What stinks with that part is that the fault is no doubt a weak rubber seal that if you held it in your hand would guess about 5 cents for it. The metal bore must be perfect and would be "honed" and other rubber seals in a rebuilt. I don't rebuild my own and never did. I have taken them apart and the slightest thing wrong could cause you an accident.
Nacho did mention to me that for the A/C the part(TXV) from Honda might have the best chance. It's so hard to say with parts. The car maker doesn't even make their own parts for lots of items but you would hope they have a strict quality control on what they do sell??

Tom,
I'm thinking in importing this brake part !! I can't afford for the prices here at the moment!
Could you help me for this?
If I can, I will buy the expansion valve as it costs only US$ 25,00 new at eBay.
But I would like to do it in one package to pay only one shippment.
I didn't find the master cylinder that you mentioned. I found one at $ 114 US
But what kind this product is ? Brand new???
Is it reliable? I don't know about that brands...
What do you think about buying one of them?
And about the expansion valve, do you know this model?
http://cpwstore.carpartswholesale.com/.../Expansion_valve.jpg
I think that's different from the one I saw in my car. As my car is second-hand, I don't know if the other owner adapted another valve. The model that I saw is smaller and with some tubes... I think with a Hg bulb too.
Thanks ...
Rodrigo.

Rodrigo,
Let's take this off the open web as if you are going to get parts by mail it will need to be from different places. It worries me that for A/C this model year is tricky as the world was changing over refrigerants that year. Nacho has told me that these can be troublesome and to get the Honda part would be the best bet. I have no connections with any Honda dealer.
ACSource can get and ship Dealer parts from Arizona.
I was surprised to find when surfing that the master cylinder can be tricky also. I made the one call to my own local parts place. I didn't ask but I believe the part it new not rebuilt.
There could be issues with your car which is still popular world wide but there could be differences than ones made to be sold to the US. I worry about the mess it would be to get a wrong part by mistake.
You will need to know the real VIN (vehicle identification number) of your car and the month it was made which is usually on a sticker on a door jam - usually driver's side for cars here. It should match one that you can see thru the windshield in case the door has been replaced for some reason.
There should be a great advantage to buying things for you in US dollars now with the dollar a record low value vs other money. It may save taxes but I don't know the rules for Brazil.
As for Ebay - I don't know how you can know thru that system what you are really getting.
Look for a Private Message and if it doesn't work try to send me one - it will show on lower right corner of your computer screen if you click on my name above the cat if you didn't notice that feature of this site.
See you there,
T
