Had to abort a trip to Sussex last Sunday at Roehampton Vale, where I became very aware of a dragging brake. In the petrol station there, the o/s front wheel was nearly too hot to touch. The AA sent a local proxy with a get-you-home truck which got us back here. On Monday took the car to my fine Aussie indy near here.

He said the o/s disc had taken some punishment and anyway had corrosion on the inside braking surface. They weren't exactly free and neither were the pads. Twice what they would have cost for the Escort or more. When fitting the pads he found the cause of the binding that had stopped us: corrosion, he thought, as a result of the brake fluid not having been changed, causing the piston to stick. The resulting heat would (in my own opinion) have exacerbated the dragging. So, a new caliper too. I had hoped the problem was just seized guide pins, but no such luck.

Exchange caliper retails for £145. My man charged me two thirds of that, passing on his own discount to me. He charged 50 quid for labour, too little really. He's a jewel. But it still cost a whisker over 300 quid, and being a patriot to the bone I am pretty skint right now.

Ah I see Lud, your is old (lack of) money.

I am one of the Nouveau riche, so very uncouth with splashing it about.

'Old' be damned, lack of is just about the size of it. Money isn't everything they say, but it does come in useful quite often.

Naturally AE I am pleased and reassured to learn that you are keeping your head above water.

Just shows - you can't skimp on maintenance. If the car had had a brake fluid change at the correct time (which one assumes is part of the maintenance schedule at mileage/age) it probably wouldn't have needed the new parts.

Not saying it's directly the OP's fault, but even older cars need schedules adhered to and/or checked for completion. But I suppose it's a bit of a Faustian pact anyway with older vehicles of (in the maintenance/servicing sense) uncertain provenance.

My Father ran a Polo C for the best part of 17yrs without a brake fluid change - no problems with calipers.
Next doors old Golf had done over 12yrs too.

No one bothers with brake fluid - only `enthusiasts` ;-)

Fine when you're pottering around, but the one time on the motorway when you need to stand on your brakes at 80mph to save your life, the accumulated water will boil merrily as your foot hits the floor - "No one bothers with brake fluid" an amusing epitaph.

I too have to disagree with oily.

I found I had boiling brake fluid due to a partially sticking caliper piston as I reached a roundabout on a dual carriageway section of the A2.

Not funny.

The car has been serviced annually I think at the Sheffield main dealer it came from in the first place. It's eight or nine years old and still below 60,000 miles.

I don't know how conscientious the Sheffield place was. The book is stamped but not all the bills are still available. I don't know for example if it's had the cambelt change it should have had on age (not mileage). Its previous owner was my niece-in-law, a very busy, highly paid young woman. I know she got an exhaust at an aftermarket chain place, noisier I am sure than the proper part. She may have had the brakes done by chain places too.

Getting the brake fluid changed, preferably not by pumping it through with the pedal, is now going to prey on my mind. Don't want the ABS to start acting up. My man didn't do it because he hasn't got the machine.

Oilrag: speaking as one who over many years had much do do with horrible old black brake fluid with bits of perished rubber and nuts and bolts in it, I really can't agree!

Good point the main reason for (mechanical) ABS failure is corrosion due to missed fluid changes.

PPS, I use Castrol Response Super DOT 4 (5.1 synthetic) brake fluid, cheaper from Sainsburys Homebase than in Halfords. this stuff does not damage paintwork and can be freely mixed with DOT 3 and 4. The heat fade resistance is astonishing compared to standard fluids. One of my bikes was almost unusable on the track due to brake fade after 2 laps (on fresh new fluid) Castrol Super DOT 4.1 cured the problem.

Not doubting your account, but how would a different fluid cure brake fade?

I can understand if it prevented boiling, but that's scarcely fade - when my brother boiled his brake fluid (which must have been 10 years old, in the days when nobody thought of changing it) the pedal went straight to the floor.

"Fine when you're pottering around, but the one time on the motorway when you need to stand on your brakes at 80mph to save your life, the accumulated water will boil merrily as your foot hits the floor - "No one bothers with brake fluid" an amusing epitaph."

Firstly, insufficent water will accumulate in the brkje fluid to boil
Secondly, One panic stop from 80mph will not generate enough heat in modern braking systems to boil anything.

No-one does bother changing brake fluid any more. Take any 6 year old car and I doubt that 30% have had a change of brake fluid. The roads are not littered with burning hulks from car crashed due to brake failure.

Failure of ABS systems due to not changing brake fluid? thats a symptom of crap design, aka VW.

Like others here, despite experience of what neglected brake systems can become, I have never that I can remember changed the brake fluid in a car. As long as the brakes worked I didn't mess with them.

Now I suddenly want to change the fluid. I wonder why?

Lud the car was very cheap in the first place when you buy obscure cars like that the high cost of parts will be the problem :(. You just have to hope it dosn't need many high priced parts.

None cheaper Rattolo, I agree.
obscure cars like that


Not that obscure though. There are a lot about here although perhaps they haven't quite reached the more remote northern fastnesses (or 'mimserdoms' as they might more accurately be called).

corrosion he thought as a result of
the brake fluid not having been changed causing the piston to stick.


When I was pretending to work for a Citroën indie in Bradford years ago the owner had a device that fitted on his air wrench that looked like 2 curved carborundum stones in a spring arrangement that he put inside brake cylinders and the centrifugal force from the air wrench polished the inside of the brake cylinders. The pistons of sticking cylinders were tackled manually with emery paper. A thorough clean and new seals, always new seals and they were good to go (or stop as the case may be). These were brakes fed by the hydraulics at over 2000 psi so leaks were found quickly. IIRC the doctored brakes didn't leak.

Has this highly technical solution fallen out of favour ?

I use a similar system to recover Jowett alloy wheel cylinders. a short wooden dowel with a slot about 2 inches long. A short length of soft cloth is gripped in the slot and soaked in T Cut.
A short time in the drill polishes any imperfections out of the bore.
Done it for years...very efficient.

You are talking about a honing device. This is ok if there is very mild imperfections in the cylinder, but usually they are pitted and exchange is needed.
I doubt moisture caused the sticking.
Brake fluid should be changed every two years and most cars we see do have it done. It is not expensive and a firmer pedal usually results because there is nearly always a little air gets into the system over a long period of time/ Also particles off seals get into the fluid and can cause problems with ABS units, the Nissin units (not NISSAN) fittend to some cars like Hondas and Rovers are prone to getting troubles with dirt in the fluid so always pays to keep it clean.

I did put a smiley at the end of my throw away comment ;-)

Actually, my Father refused to let me change the fluid on the Polo. He had the last laugh on it though in the end.

I change mine every three to four years. Or rather let the garage do it. Fiat dealer charged me £25 last time - not worth messing with the bleeding tubes and Gunson kits.

I also lack motivation in this area of DIY due to fear of getting air into the ABS unit.

Having suffered a sticking brake cylinder I am a change-every-two-year man.

My problem was on a 1970 BMW 2-pot caliper. Having removed it from the car I couldn't get out the stuck piston. Decided to put a plate over the "good" piston held in place with a g-clamp. Then filled a Wanner grease gun with braked fluid and pressured the caliper. This caused the g-clamp to snap in half!

You used to be able to get sets of rubber seals for brake calipers and cylinders. Perhaps you still can. But they are probably harder to get than new assembled units. They too won't be free. And then there's the labour: take the whole thing apart, fettle with glass paper or whatever, clean very thoroughly, reassemble with new seals, then install.

I didn't blame my man for not doing it. I know though that he could have done it (as I could myself). But it might have cost more in the end.

By the way, bits even for Chryslers are a bit cheaper on line. But there's a time factor.

I once fitted a new wheel cylinder on an 850 Mini and re-rubbered the other side. (as I had a kit in my toolbox)
The new cylinder failed before the re-rubbered one!

Yep i've replaced seals on dozens of brake and hydraulic clutch systems over the years, including master cylinders though never tackled stripping an ABS unit nor likely too.

Never had a problem afterwards, but found much gunk mud and bulletts floating around in filthy sometimes rusty (water) muck once known as brake fluid.

I wonder if lack of maintenace led to accelerated wear on hydraulic seals etc, unadjusted drum brakes pistons having to travel their whole length in the slave cylinder, much longer travel on the master cylinder too must have taken their toll quite apart from filthy muck being pushed through the system causing increased wear.

I imagine getting repair/overhaul kits for vehicles not being as easy as it once was.

Only 2 bottles of Brut this weekend then Lud..;)
