Changing Brake Discs

[fixitflav]

now I'm confused.
Videos showed Caliper held on by 2 machine screws and Caliper fixed frame also held on by 2 machine screws

Found a link to parts schematic https://tinyurl.com/yucy8rjx
It shows no such fixing screws for the Caliper assembly .... refers to unit as 'floating Caliper brake'

Shows a guide pin & bush (item 7) ....anybody know what holds these pins into the Caliper Carrier ? ae they screwed in ? ..... maybe end of them has a hex or torx socket
It does shows complete assembly is fitted to axle by bolts (item 8 ) but no part number listed.


Anybody worked on these brakes ?

Your link didn't open.
Just looked at the earlier video. I've always been against electric parking brakes, and that confirms it. What a ridiculous performance to do what should be a straightforward job! Presumably there's a reason for it, but I can't see why the battery charger is needed, if the battery stays connected, as it does.
And the idea of different torques for the upper and lower mounting bracket bolts, whatever next? How do they think the majority of people who don't bother with a torque wrench get on, and seem to manage OK.
I don't know how old the video is, but the last ones I did, about 3 years ago, the new discs were coated with aluminium, which disappears in the first few miles, so no degreasing needed.

The caliper bracket will be held on with two bolts of some description.
The caliper is held to the bracket with two bolts also.... maybe they are allen bolts in a sleeve with end caps on?

The diagram shows a guide pin .... no bolt
Now that may well be screwed in but no experience of this form (yet)

Check post 27, item 7 has a thread on the end. It screws in. Bring it to Hampshire week after next and I’ll show you how to do it.

The guide pin (No7) is the bolt. That’s the one you need the 7mm Allen key for.

All Allen key bolts on every brake on every car I know are 7mm.

Mine too - but it is a size which is missing from the usual set of keys.

Yeah, I’ve always found that strange.

Remember these original sliders.....they used to slide within a steel guide so seizure was almost guaranteed.
Thankfully they now slide in a nylon sleeve. Best to use a 3/8” drive ratchet with the allen socket to shift them.

On the Mondeo they are ordinary bolts with either 12mm or 1/2" AF heads.

So not Allen key bolts then. I don't think you’ll find imperial sized bolts anywhere on a Mondeo!

 

[Stivino]

Replaced them with proper bolts, 19 and 17mm AF.

I’ve been looking everywhere for 17 mm AF bolts.
Where did you find them?

The bolts aren't imperial, I think they're probably M8 fine, the thread is finer than standard M8, 1.25mm pitch. Of course it doesn't matter as long as they fit the holes in the mounting bracket.
M8s are a bit peculiar I find. My data says head AF is max 13, min 12.57mm, but a 13mm spanner is nearly always a sloppy fit and 1/2" AF is better. Doesn't seem to happen with other sizes. Then Ford compound it by having plenty of non-standard head sizes, like 12mm here, and for the caliper mounting bracket bolts I mentioned before.

I suppose you mean standard M10? Got mine from local ironmonger. Grade 8.8, bright zinc plated.
Amazon.co.uk : m10 bolts

Wasn't aware it had a 'allen' socket on the end, now I am , I have a way forward.
On item 7 as well as metal pin it has a 'bush' presumably some form of plastic bush. Do you need to change them? or just remove & refit the pin.

 

[Mottie]

Just remove and refit the pin.
