xmission Posted November 5, 2020 Report Share Posted November 5, 2020 I ordered a set of calipers for my 91 esprit from our local autozone store. I got a left and right for a 1984 Toyota Celica. There are slight differences though, most noticeably that the brake line connector comes in at a different angle. I'd have to bend or replace the brake line to make it work. I think they will bolt up fine physically, except for the brake line issue. Have you guys had this happen, or does it just sound like they are wrong?

lotus-62 Posted November 5, 2020 Report Share Posted November 5, 2020 my '85 esprit has the celica calipers as well, they are 57mm in diameter, as long as the bleed niple is on top, why not? Quote Link to comment Share on other sites More sharing options...

xmission Posted December 28, 2020 Author Report Share Posted December 28, 2020 I wound up with the wrong calipers the first time around. I was able to find pics of what they were selling at one of the bigger parts stores online, and was able to match the casting number on the caliper, and was got the correct ones the second time around. My Esprit is waiting for spring now. Essentially ready to drive. I am mulling over that electric power steering mod though... Quote Link to comment Share on other sites More sharing options...

Ive just been refurbishing mine. I wanted to get some new stainless steel pistons as my old ones had corroded a bit and caused a sticking brake. I couldnt find anyone selling them. Sillilar ones not non that would suit. So Ive just machined a pair up. buddsy 1 Quote "Belief is the enemy of knowing" - Crrow777 Link to comment Share on other sites More sharing options...
lotus-62 Posted December 29, 2020 Report Share Posted December 29, 2020 Buddsy, I've never seen the stainless ones for the toyota calipers! I went for the nissan calipers/peugeot disc setup (I needed new discs and an overhaul on the calipers anyway) I would love to know how you did the outside diameter on the pistons as I need 1 new piston for my spitfire that has the blmc princess setup, I have a mill and a lathe but just wondering on the tolerance and surface roughness. rick Quote Link to comment Share on other sites More sharing options...

Ive got a pretty decent cnc lathe which I can hit tolerances I couldn't achieve as consistently on my old Colchester Lathes. Surface finish too is very fine. We still grind some items but not very often these days. I aimed at making my piston 0.01mm bigger than my existing to allow to polish the surface. Used a bit of P600 then P1000 then a bit of the old scotch bright. When thinking about what size to make the new pistons although I didnt want them loose I didnt want them tight either as last thing I wanted was the piston to become tight once it has some heat into it although the piston and iron caliper should be about the same temp and expand roughly the same. After some polishing the piston finished +0.0025 In the caliper it feels a little loose if anything but since my old ones weren't leaking Im hopeful these will be fine once the new seal kit is fitted. buddsy 2 Quote "Belief is the enemy of knowing" - Crrow777 Link to comment Share on other sites More sharing options...
lotus-62 Posted December 29, 2020 Report Share Posted December 29, 2020 oeps we are hijacking..... I have been thinking about a ad-on for the lathe to be able to grind down parts. something to think about this winter. thanks for the explanation! rick Quote Link to comment Share on other sites More sharing options...

( I made my own lathe and mill, had so much fun doing this) rick 1 Quote Link to comment Share on other sites More sharing options...
Buddsy Posted December 30, 2020 Report Share Posted December 30, 2020 A few pics as we all like pics 🙂 And the old grinder on which Ive done a fair few bits for Classic Team Lotus. Grinding hubs etc. buddsy 1 1 Quote "Belief is the enemy of knowing" - Crrow777 Link to comment Share on other sites More sharing options...

I sold an old one and bought my Esprit with the money. Yours has a power cross slide. Very versatile machine. You can get a slotting head for the rear which spins round and a 6" riser block. Some of the digital readouts have come down in price and are a good addition. buddsy Quote "Belief is the enemy of knowing" - Crrow777 Link to comment Share on other sites More sharing options...
