No seriously I did remove the drums and it wasn't an easy job mate.

Once you had stopped did you pump the brakes to see if they came up. It there any pedal resistance other than the reoturn spring. Is the clevis pin and servo acuator still in place. Come on do soem basic tests first and tell us. Regards Peter

The thing is mate That all this happened while I was on my break. No time you see. I did take a look at the reservour and saw no loss of fluid. I did pump the pedal and found little resistance. I'll have to wait till tomorrow and check then, luckily its a national feast. Unlucky for me I'd have to stay in garage with the rest of the family enjoying the beach. Life's a joy isn't it! :(
Thanks for the clevis pin and actuator tip though. That's what I was after mate some ideas to start me off. I'm not full time mechanic you know, just someone who loves to do his own stuff, not on a holiday that is :)

Sounds like the brake master cylinder seals have gone.
|
|
Funny that both circuits of the split brakes went at the same time.
|
|
That's why I didn't go there on the assumption a MK 3 has dual cct brakes. Regards Peter

The only real common part in the system is the master cylider thats why I suspect that ,plus there is no fluid loss,
|
|
I have come across a few master cylinders that are very difficult to see whether both reservoir chambers are full of fluid, on a split system, such as on a tigra. So it looks full, but one half has drained. If one half of a split system fails, my experience is that the brakes are terrible on 2 diagonal wheels.

I have always found, when the seals go on these they all go and dont give any warning.
Just my experience of these cars

got to say im going against the flow as i have never replaced a master cylinder on a mk3 fiesta,ive always found them bulletproof.
leaking rear cylinders hundreds mind........

Sorry for the late reply but I was on vacation till yesterday. The visible faults are as follows. On later inspection the rear driver side wheel was found smeered in hydrolic oil indicating the fault was from that side. On rear brake drum removal, using the four bolt method, one shoe was found with the pad removed and the wheel cylinder piston almost fully out and leaking oil. I asked my father to buy me an oil seal set since the car is now more than 10 years old and thought of replacing both sets of rear wheels whilst I'm at it. I'll also be replacing the shoes of both ends of course but sadly no brake shoe replacement parts are available till next week! My father bought me the complete wheel cyclinders as he saw them cheap but I saw the job a little complicated as it seems you need to remove the whole wheel back plate to do so.
Couple of questions:
A: Is it possiblt to remove the rear wheel cyclinder units without removing the back plate. It seems to be attached to the rest by means of two rivets. Are these common revets?
B: Maybe I should remove the rubber from the new items and replace the old with these?
C: Is it possible to have no brake pedal pressure when only one wheel cyclinder fails or do you think I have more trouble than that already found? The thing is I can only tackle one wheel at a time due to limited garage space. I can only attack the other end only after completing this end as the other side is against the wall now!

Isn't this a bit exagerated? Remeber if you buy a rubber replacement kit you'd be doing just the same.
If the old cylinders are without scratches I can't see any harm, even Haynes suggests this!

When complete cylinders cost less than £10 it's really not worth the bother, and why strip down nice new shiny cylinders and stuff the internals in old grubby cylinders?

We retail MK3 Fiesta Wheel Cylinders at 7.67 each +vat. Why mess around? Also, it's brakes you are messing with, if you are not sure how to do it, get someone in who does.

to even consider swapping parts is deadly, i would be arming myself with 2 cylinders set of shoes and a replacment spring kit and a tin of aerosol brake cleaner [ dont breathe the dust] and would be expecting problems with pipes that go into cylinder. i really think you should be farming this job out .

NOTE: I've never worked on these brakes. The following is based on extraction from Haynes (which I suggest you purchase zunkus).
A: Is it possiblt to remove the rear wheel cyclinder units without removing the back plate. It seems to be attached to the rest by means of two rivets. Are these common revets?
You will need to drill out these rivets to remove the backplate/shoes. Note the handbrake cable will still be attached, so complete removal is not possible. I suspect the rivets are common, but for peace of mind I'd be inclined to buy the rivets from Ford. I assume you have a pop-riveter?
Before undoing the cylinder securing bolt, expand the brake shoes by pulling their tops away from the wheel cylinder. The automatic adjuster will hold the shoes clear of the wheel cylinder for ease of removal.
Remember to clamp and bung up the hydraulic lines and bleed the system through afterwards using Gunson's Eezibleed or similar.
C: Is it possible to have no brake pedal pressure when only one wheel cyclinder fails or do you think I have more trouble than that already found? The thing is I can only tackle one wheel at a time due to limited garage space. I can only attack the other end only after completing this end as the other side is against the wall now!
Replace the other cylinder as it will probably be in a similar state of repair as the other one. As for the total loss, your brain may have been playing tricks on you thinking all was lost when in fact one circuit was still working. Braking on one circuit can be just as scary and disconcerting as braking on none - believe me I know!
Hope this helps.
