Brake Caliper question

Recent MoT highlighted that OSR disk was showing signs of having been hot, but neither MoT tester nor myself found it hot when checking after driving. I have on occasion noticed a minor squeak when starting out for the day, but it went away after just a few metres each time.

However ... since then I've felt on a couple of occasions that car pulls slightly left on initial application of brakes but sorts itself out.

Last Thursday, it was a noticeable there was a delay in full braking force coming on AND when I reversed shortly afterwards, the squeal was much louder than previous instances (and wouldn't normally have happened at all having already driven for a while).

So I've spoken to the garage and will get it done in a week or so when slot is available.

Suggestion is it's going to be a new caliper and I get it that that's best/safest/quickest fix (although if I was up to doing it myself, I'd do a refurb).

The real question is should I also get the flexi-hose done at same time ? car is now 11 years old and I doubt they've ever been done, but is it adding a load of time/expense to the job ? would I need to get both sides done ?

Any thoughts/advice oh wise ones ?

The brake hoses are relatively easy to change. You’ll have to bleed the system anyway so there is not much time being added with that. If you intend to keep the vehicle forever just get a set of stainless steel braided hoses. HEL makes a D3/D4 kit which includes everything and you get to choose the color Whistle

I would recommend changing all the hoses at the same time but that’s just me. DIY it’ll be an 1 - 1 1/2 h to change.

I got a brand new caliper from AF delivered in a few days to here, so I’d assume you can get one faster there Laughing

I don’t think it’s worth to refurbish a caliper yourself but YMMV of course. In my case they would not have been, I mean.

Problem could be as simple as the caliper slide pins needing regreased/replaced if they've never been done.

Older cars regardless of make, the brake pipe is usually rusted within the brake fitting and the whole lot turns when you try to remove it from the flexible hose, then its a new pipe or repair as well.

not worth the hassle...your trying to stop 2.7 tons...just fit new and ride with confidence...if you tow the load is far more clearly

I would also inspect the brake lines just north of the flexible pipes as well… specifically check the lines where they are clipped to the body… there is normally a foam liner which protects them but retains water which make them rust.. if yours are original then they probably need doing!

Garage had a cancellation and called me earlier, so it's gone in today. Caliper that turned up is genuine LR part ... but it's on an exchange basis so bang goes my idea of cleaning the old one up and sticking it on eBay Sad

It had new pads/discs all round about 12 months ago so unlikely to be the issue here.

all done.

problem was piston seized in caliper ... brakepads shot, so new set on the back wheels.

£160 all in. Sad


My "bargain" wheel nuts turned out not to be a bargain ... mechanic tried them but "they don't feel right" and put the old ones back on. Have to see if eBay will refund.
