What did you do to your MX5 today ?

[peteh]

Then use red rubber grease (instead of copper) apparently, I dosent damage the rubbers around the brakes

[Steve]

I've read this alright (causing seals to swell), think it might depend on the type of rubber used, I've not had any problems in the years I've been using it on the MX5/other cars.

[ger]

rear driver's side brake was dragging (wheel getting v.hot).
Did some slathering, adjusted it, tested, problem worse. Did more adjustment, seems much better but not convinced its fixed completely yet.

Had this problem it turned out to be the handbrake adjuster beside the caliper. Get someone to pull and release the hand brake and see if the mechanism is moving freely at the back of the caliper.

If its not then remove the 14mm that steve mentioned then get a 4mm allen key in the hole, there is an adjuster in there, wriggle the allen key around and pull and the adjuster will come out its splined so easy to put it back. Spray some penetrating oil in the hole and work the hand brake lever at the back of the caliper where the cable ends until it springs back easily. worked for me.

[Steve]

Nice one, could be that. Will give it a go.

Fitted a set of ultra racing fender braces during the week, seem to have strengthened up the front end, bit less wobble!

[leamyj]

oohh..haven't seen that before.... very interesting indeed!
Good job!

Finally fitted that car alarm thats been sitting in the back of the wardrobe for the last 2 years.
Just need to set up the remote start now.

I washed mine and then had a little (read:major) freakout that the clear coat was coming off until I realised that it was wax that was in with the detergent just dried in.

Haven't had much time with work but I put a few of my old fives parts on the new one. Gave her clears all round, removed old rusted grill and replaced with my polished one and then just gave her a good machine polish today.

Next job is to do the audio....

Nice one, could be that. Will give it a go.

Did all the above, brake still sticking, took it apart again last night, regreased and readjusted, had someone push brake pedal and release to check it. It kinda looks like the caliper is rubbing on the disk. Will run it for a day and see.

I had a sticky caliper on the front, managed to sort it out by carefully pumping out the pistons while the caliper was off, folded back the rubber boot cleaned it well with brake cleaner and a toothbrush, lubed the piston with brake fluid and used a g-clamp to push the piston back in, worked the piston in and out a few times until it was running free, still going 1 year later.

Should be easier to do this on the back as you can wind the piston in and out with an allen key.

[Steve]

Thanks Ger, yeah I think I'll give that a go, at least I'll get a look at the condition of the piston. Will order a rebuild kit if it needs more than a clean.

[ger]

You can get a fair amount of the piston out without losing the seal, just be careful not to pump too far and you wont have to bleed, remember to unscrew the reservoir cap also. Stiction in the rubber seals as they dry out is a problem and the fresh brake fluid helps to free them up.

[Steve]

yeah, cool, that makes sense. Wasn't looking forward to getting the piston back in past the inner seal.

[Steve]

Replaced the neurotic battery I had for a new Westco. Big difference in cold starts!

Attacked the brake again, pushed the piston out a fair bit (stuck a bit of wood in the caliper to stop it popping completely out), pulled back the boot and slathered it in brake fluid. Tough job to get it back in but its in and seems to be working perfectly so far (couple of 10 mile spins over the weekend). You were right about the piston Ger, dry and sticky, so presumably the seal was too. Must change the brake fluid this week am sure it was boiled a couple of times.
