brake caliper tool

[stuvy]

Just for those of us without the knowledge/experience/confidence for brakes work [caliper overhauls etc], I give you.........http://biggred.co.uk/ I've no personal experience of them, but have read good reports elsewhere.



Not a problem if you're prepared......

that bloke must have the most tedious repetitive jobs ever!

have you been chasing butterflies in the garden @slim_boy_fat

They do excellent work, I've bought parts from them as they are only about 35mins from me.

brakeparts.co.uk are another good source and their rebuilt calipers can be surprisingly cheap, often cheaper than buying all the parts.

I was once holding a Lancia single pot front caliper my fingers wrapped around the opposite side while blowing the dust of it with an air line . . . air entered the hose connection opening . . . piston shot out, hit my fingers, cockle-ed over and jammed . . . it would not push back, meanwhile my fingers are rather hurting . . . it went in the big vice on the bench next to me and it WENT back in! Not harm done and I didn't hold a caliper that way again!

Currently hunting down a seal kit to a very similar caliper to that Audi one - 36mm dia piston, same hand brake mech - according to Brakes Int they can't get it . . one supposedly in London turns out to be coming form Lithunia . . . currently 3 weeks and counting . . .

I've done a similar thing with a caliper and got away with it, you never ever make that mistake again because it scares the life out of you.

If you type 36mm seal in the brakeparts.co.uk search it brings up quite a few things, interestingly one is the Audi Quatro. It's entirely possible you could find a seal that way even if they don't list one.

Places like Biggred often don't even need the vehicle details they will go by dimensions.

I'm glad you posted that, I sourced some master cylinder bits for a 50 year old forklift and couldn't remember where, pretty sure it was them. Weirdly I can't see any contact details on the site.

cast iron turning is easy but incredibly messy...

Big round magnet in a plastic bag, strategically placed, can help a lot.

View attachment 225744 These didn’t want to come out with air so had to resort to pulling them with tools.
You may notice the end of the piston on the left is bashed. This was the previous owner who taken it to a garage and they charged him for reconditioning the rear calipers that were binding. Reconditioning must mean smashing the hell out of it until the piston goes back in the caliper.

think if it was that bad id be welding a big bolt in it and pulling it out
once that plating is gone its the bin
stainless pistons and sleeved bores would be better , they move so little so never realy have a chance

these seals were bought from lucas service
when they were still on the go

Pistons were trashed so in the bin they went. The bore was unmarked but the piston wouldn't go past the seal hence the need for a touch brute force. Cleaned up and rebuilt with new pistons, seals, pins and rubber boots from Frentech Components in Burnley. New discs and pads, they were mess. Now they work perfect.

Now there's someone who expects their moneys worth

everything cleaned up and a good coat of industrial wax unbelievable nick for 33 yrs

 

[Stupoty]

you can do that but if your on the bench an airline is always to hand as @Alan Reynolds mentioned a cloth to stop it firing into next week

yeah I mostly just remove them for, errrr, fun when I'm supposed to be changing pads or discs

 

[slim_boy_fat]

industrial wax

"Nuclear grade"

Grease nipple can be substituted for Schraeder valve if air is not available.

tried this today on an old two pot one my gease gun hose screwed directly into the caliper ,bit messy but certainly pumps them straight out with no effort , air method wouldnt shift them

 

[ranchero]

i use a herald master cylinder its mounted on a angle iron bracket with a big lever to operate. it pumps out the piston with no drama

Much safer too

 

[JohnH]

Sometimes even a grease gun wont remove them, so I find you can walk them out by gently tapping them side to side.





Believe it or not, they were stainless pistons, that cleaned up ok.

That’s where brake piston pliers come in handy, especially with opposing pistons
