Excellent thank you Alex - that's the right shape, I just one that is a bit longer now.. the design of the TBO requires the arm to be about 3cm longer (need to measure exactly still).

The cable seems to travel alright but there is a sort of grinding feeling. Hopefully lube will improve it. Do you lube from caliper side or from inside the car?

Quote from: Alex Knight on Today at 07:50Sorry. I've just realised that the second pic is from your Celica! D'oh!

Yeah, top image is the MR2, below is the severely whipped Manky Celica! The 2zz is the worst sludgy engine I've ever seen by quite some stretch!

The cables have a ptfe or similar liner & are not designed to be lubed, but a thin oil works. Undo the support forward of the caliper to get the cable-end down low to encourage flow.  Start with a wd40-type with a straw. Then 3in1 oil or similar. First time I did it was 2019, the cable needed gripped with pliers to move. I've lubed it again since, and it still works.

I have high parasitic current on my car too. I have to disconnect the battery if I don't drive the car for a few days. Will check this out

Thanks for the replies. I've ordered a new rear-right caliper off Ebay, wasn't too expensive - hopefully it will fit fine. The rear-left caliper looks like it was replaced, while the rear-right looks original. What type/brand of lube would you recommend for the handbrake cable? I'm Hoping I won't need to change the whole cable lol

@Dagnet
Here is a link to the How To do a "Full rear caliper strip down and repair. Hand brake issue".
It is very clear and comprehensive. But be aware that you will need some tools, that you may not have, that will cause the cost of the exercise to be increased somewhat above the cost of the replacement parts.
It is worth reading just to get an understanding of what is/ supposed to be happening when the handbrake is applied.

Quick on the draw @Ardent beat me to it!

As above.

I looked at rebuilding refurbishing a set of calipers.

 By time I had factored in the tools I would need to buy to complete the project.
Was not cost effective for me.
I just bought pair in the end.
