Which calipers?

Recommended Posts

Has anyone got any recommendations for new front calipers for a Td5?

What brands and/or suppliers would you suggest from your own experience?

At the last MOT the tester said that one of the front calipers was sticking a bit, so I'd originally intended to rebuild them both with nice new stainless pistons. But looking at the prices of new/recon calipers, I'm thinking I may as well save myself some hassle and just stick some new ones on...

I have had ap calipers on my 300TDi 110 for seven years. They seem to be working well. I have been doing a major service and wanted to check that each piston is moving. The discs looked good but I still wanted to check.

So I removed the pads in a caliper and then wedged them so that only one piston could move, then pressed the pedal. This moved it out and I could wipe and apply a little red grease.

Depending on the condition of yours this might be all you need to do, as well as cleaning and greasing the pins and other sliding bits.

Thanks for the replies so far.

I might at some point rebuild my original calipers with stainless pistons as I mentioned in the first post, but right now I'd rather spend the time doing something else, which is why I want to get some new/refurbed calipers I can just bolt on.

I'm thinking the AP/Lockheed OEM option is top of the list, and the prices aren't too bad from LR Direct, if I can ever work out which part number I need!

But for balance, has anyone had any experience with some of the cheaper options?

Service them, no overhaul, just remove pads and clean and grease to be sure they slide. Or have you done that and they are still sticking?

Thought I'd take the wheels off and give the calipers a service after a few of you suggested I do that before buying new calipers.

I think it's fair to say the pistons are Donald Ducked...IMG_20220312_123739733.thumb.jpg.2766c2bd10631966a193e48904963b03.jpg

The dust seals on the upper, inner pistons on both calipers had come adrift and the pistons were stuck. I managed the free them off and stick it all back together but I shall be ordering some new AP calipers as soon as I can work out the part numbers!

I’d call Zeus Engineering to ask how quickly they can get a stainless piston set to you - I paid a bit over £100 a decade ago for a set (and another about five years prior).  The quality is superb and it’ll mean not doing it again, as opposed to a new set of callipers that will be like this in five years time.

There's no great rush. I will probably rebuild my calipers with stainless pistons at some point. I'm just not sure I want to have the truck laid up for the couple of weeks it would take me to strip, paint and rebuild the calipers 🤔

How do people get on with fitting the dust seals without the special tool to press them in?

I've rebuilt plenty of calipers over the years from Brembo F40s to 6 piston bike calipers, but none of them needed any special tools to fit the seals!

Britpart do a piston/retainer ring fitting tool, it can also push the pistons back into the caliper body https://www.britpart.com/all-parts/da1153

I bought mine via ebay IIRC.

or look on https://britrest.com/ Mike has some caliper piston & retainer ring setting tool diagrams 2 links on https://britrest.com/shop/ 1st is in Metric & 2nd in Inches.

Genuine retainers fit far more easily than Britpart, which are not pressed as neatly and catch on the lip.  Filing the edge to a small bevel helps, as does fitting the seal and retainer with the piston fitted and protruding to guide them in if you don’t have the proper tool.  Worth having some spares to replace any you damage.

I fitted some AP seals and retainers last week with no problems and without the tool. I tend to just use a big washer (radius arm washer) and a g clamp

 

It is also significantly easier with the piston split in half which I had already done to shot blast them

I've already got some Lockheed/AP seal kits so hopefully they will go in without the Britpart tool. I would normally buy the right tool for the job, but £70 for a piston spreader and a bit of turned metal seems a bit steep!

Not all kits come with gallery seals for the caliper halves, and the vented ones with spacer are an absolute bugger to get. Split with caution…

Shop4autoparts sell them (theres no part number whenever I have looked but they are on their site)

 

Big Redd will also do them if you send them the dimensions (that does mean you have to have had them apart to do that of course).

Last time I searched they did not have them available.

NON vented & rear caliper half gallery seal 

Vented caliper tubular seals but no metal inserts

Both of the above show -- OUT OF STOCK, so probably best to ring them.

I managed to obtain some of the vented caliper seals from BiggRedd a few months ago,I rang & spoke to the guys there.
