Replace brake calipers as a pair ?? - the_bandit
Backroomers,

I have been advised my local main dealer that my OSR brake caliper has been seizing on and has now worn the brake pads down to a very low level. Not disputing this as the brake pad sensor had already triggered the warning light.

The discs were on the way out anyway so I'll be needing pads and discs but the dealer insists that they always change calipers as an axle set. He kept going on about new and older calipers on the same axle as potentially having differing "strengths" which may upset the brake balance.

Now I've heard about and understand changing say shock absorbers, brake pads, discs etc... but does this really apply to brake calipers? Is the dealer selling me down the river bearing in mind these calipers are priced at £180 each?

The Bandit.

Yep I'd say he is selling you down the river, I have never seen brake calipers changed as pairs just because one is broken. And also why is the brake caliper seizing on? It may just need a little bit of attention and fettling, such as the caliper slides may require cleaning up and greasing, rather than it being beyond repair. What car is it on and may I suggest you seek a second opinion at a different garage.

It's a '53 plate Galaxy TDi, 60000miles.

No, calipers can be changed individually - obviously the replacement has to be of the same design. The dealer is trying to scam some money off you.

Replacement calipers for these cars (there are two types) are under £100 each. You will also need a new set of pads (both sides must have the new pads) - about £30 tops.
Allow 1 hour labour max to do the job. An independent would be better than a main dealer on this job.

Before condeming the caliper it should be checked over. Often the pads stick in the slides and a good clean up, some copper grease and new pads will fix it.

Just ask the dealer what would be replaced if the repair was covered by the Ford warranty.

I had a rear caliper replaced on my Mondeo under warranty at about 20k miles, the new one was exactly the same as the old, if the design had changed then cleary two would have been required. Also I understand that they change front ones in pairs. The Mondeo suffered occasional sticking calipers on the rear cured by a service kit that facilitated extra silicone grease on the sliders, perhaps this is available for the Galaxy.

Another point, the Galaxy brakes are surely VAG parts, perhaps VAG only supply in pairs.

Just to say, even if only one caliper replaced then two sets of pads requ.

I changed the front offside caliper ONLY on my xantia when it failed on the handbrake performance on the mot (the xantia has front handbrake and the handbrake mechanism was all rusted up as i believe water ingressed into it).

Seemed a bit excessive for a new caliper as the footbrake part of the caliper was fine, but the handbrake part was non-repairable-not by me anyhow. Cost £70 for a Bosch caliper from GSF.

I changed the caliper, very easy, it passed the MOT the next day, so i would suggest the garage is trying to rip you off.

BTW as your car is a galaxy maybe GSF or ECP have the part if it is the same as a VW sharan, and take to a local garage for fitting, you may save a few notes.

Perhaps the latest calipers have a different cylinder diameter, which would indeed give a braking imbalance. Why not enquire further before you conclude whether they are being honest and straightforward or not? They may know something that you don't. Remember that this is a safety critical issue.

Agreed; but even if fitted as a pair, I'd be even more concerned at such a fundamental change in front-to-rear brake balance.

The rear calipers on 2000- Galaxy come in two different sizes (becauase there are two different disc sizes). Get the right size caliper and you'll be OK. As I said earlier, you only need one and you don't need to pay more than £100 for it.
You need an axle set of pads.
Check the discs both sides and clean up the carriers, put a bit of copper grease where the pads sit and it'll be fine.
You will of course need to bleed the brakes as well!

What about if the rear caliper cylinder size had been changed to correct an existing front to rear imbalance? There could be a number of reasons (all genuine) why the dealer recommended changing both calipers. I personally wouldn't dismiss it out of hand without making further enquiries.

I think it's fair to say a second opinion should be sought on this. I'll get this done ASAP and report back.

Thanks for all the input so far.

Have you considered a refurbished unit? There are companies on the net that offer exchange calipers for about £80 each.The most reputable companies give a warranty as well. £180 each seems well over the top to me.

Rather refubish the one you have, a kit would be about £20

As has been said, the dealer is trying to take you for a ride and sell you 2 calipers when you only need one, if it is not too late get the car back and go to an independent and get the one duff one changed and don't use that dealer again.

As a little experiment, get a copy of yellow pages and find the telephone number of , say, 5 Ford dealers and their service departments, ring each one up in turn and say your car has been diagnosed with a sticking brake caliper, can they quote a price and is it OK to only replace the faulty one and not both on that axle, I am sure the truth will come out!!

Then tell your local dealer about your findings and see what they say...

That's a wild statement if ever I heard one. What's your evidence of this?

But a kit wont include the handbrake lever seals and a diyer would have big problems dismantling and reassemling the handbrake mechanism. Its 99,9% likely that its the handbrake lever that seized and causing the problem anyway.

www.brake-eng.com/ do recon brake parts and will have an outlet near you
Replace brake calipers as a pair ?? - the_bandit
The dealer did say that the handbrake mechanism was not the cause of the problem.

Personally I don't trust this dealer as far as I could throw him. When I quizzed him about how free the caliper was able to slide along its carrier and were the brake pads seated in their place correctly he just spun me line of crap which ended up with the calipers being replaced.

I don't reckon he has tested the caliper at all for any faults.

I am sorely tempted just to get some pads and discs myself, retrieve the copperslip from the garage and get to work!! I shall prove him wrong!

If you do have a go yourself you'll need a calliper piston wind back tool, the pistons need rotating as you push them back.

;O)

There's not much to go wrong with a brake caliper really. Unless the pistons or slides seize solid, or the seals start leaking, they don't generally need to be touched.

It's quite acceptable to replace calipers individually rather than as a pair. I did it on SWMBO's Fiesta and have had no problems since. When we bought the car, the pads and discs were both at the end of their lives, so the caliper pistons were sticking right out of their bores. On one caliper, the gaiter around the piston had split and the side of the piston had corroded so badly it wouldn't push back in.

I called my local factors who quoted me about £15 for a rebuild kit, but said they could do me a complete exchange (recon) caliper for £35. It wasn't worth the hassle of rebuilding it for that, so I just replaced the whole thing, bled the system through and job done! Brakes have worked fine ever since.

The price you were quoted sounds excessive, and they should also be able to offer you a plausible explanation as to why they thought the caliper needed changing in the first place.

Cheers

Does anybody know what size of allen key I will need to remove the two caliper bolts (they are VW calipers) and are there any recommendations for a piston wind back tool??

Thanks.
Replace brake calipers as a pair ?? - Aprilia
Think they are either 6 or 8mm (working from memory). But you could get yourself a set of 3/8"-drive Allens off Ebay for a few quid.

To wind back the piston try a largish pair of long nose pliers, or the key off a small angle grinder might fit. You can buy the proper tool, but not worth it for a one-off job. The pliers will work I reckon.
As you rotate the piston back, be carefull that the dust seal doesn't 'stick' in the groove in the piston and twist and tear as you rotate. Best advise is to take a small screwdriver and pry the seal out of the groover sllightly, all the way around, to make sure it is free, before you rotate.

Looks like I may need to warm up some of that humble pie and get ready to eat it !

I replaced the pads and discs today. Both pistons wound back no problem at all. Wire brushed scabby bits and re-applied the copper ease where necessary.

The OSR clamp is still jamming!! It's not the hand brake cable as the mechanism is moving freely up and down. I even disconnected the handbrake cable on that side just to prove.

As another possibility, I slowly released the bleed screw on the caliper to see if that would free it up but no different. This would have pointed towards an internal break down of the flexible brake pipe.

Looks like a new caliper then after all !!

Replace brake calipers as a pair ?? - Simon
Are they sliding calipers on this car of yours? From what you have described there is little else that could be wrong apart from the fact that the caliper may not be sliding properly. If this is the case it may be wise to look into the reason why. If there are any, did you have the caliper sliding pins out to clean and lubricate them?

You mean the handbrake lever on the caliper is'nt returning to its stop?

Have you asked aboiut a repair kit? For the Mondeo you can get a kit with new sliders, silicone grease etc, about £25, the answer if the hydraulics are fine. The Galaxy is a VAG part though so kit might not be available.

You'd be better off having a hexagonal bit that you can turn with a torque wrench.

I thought you were referring to the dealer, and didn't realise until I saw another post of yours further down the thread that you were actually signing off!
