pauldoug Posted January 6, 2014 Share Posted January 6, 2014 (edited) tried to replace my rear pads today myself, everything went well, even got the piston pushed back with little effort. My problem is the dust seal is protruding around the piston, this will probably tear if I try to slide caliper back over pads. Ive tried to push it back in with no luck. Also tried to lever the boot to the side incase theres an air pocket. There also seems to be a little fluid leaking from around the seal, is this normal when changing pads, thanks for any help guys. also the inside pad was badly worn more on one side than the other.

Nic Posted January 6, 2014 Share Posted January 6, 2014 There shouldn't be brake fluid getting past the piston seals, sounds like it's split. You'll need to replace the seal, caliper rebuild kits are available from Toyota and other brake companies, each kit includes everything needed to rebuid a pair of calipers. You'll need to know which brakes you have fitted, the Supra was fitted with 2 options the larger 4pot front/2pot rear and the smaller 2pot front/1pot rear, see here for pics. http://www.mkivsupra.net/vbb/showthread.php?249089-Supra-Brake-setups&highlight=brakes Quote Link to comment Share on other sites More sharing options...

Nic Posted January 6, 2014 Share Posted January 6, 2014 that's what I needed to know, thanks nic. If you need part numbers for the Toyota rebuild kits let me know which calipers it is for, or you could try http://biggred.co.uk/ I've used their rebuild kits and they are OEM quality.

pauldoug Posted January 6, 2014 Author Share Posted January 6, 2014 Ive just emailed Big red 5 mins before reading your comment, hopefully get a good quote and have them sent away asap. Fed up with caliper problems, that's now the 3rd corner causing me issues. If the price is reasonable i'll send the 4 corners off. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 6, 2014 Share Posted January 6, 2014 They're getting very old so its to be expected, there's another company doing refurbished exchange calipers. http://www.brakeparts.co.uk i think the 2 piston fronts are approx £85 each if you exchange for your old ones Quote Link to comment Share on other sites More sharing options...
Scooter Posted January 6, 2014 Share Posted January 6, 2014 afaik the refurbed calipers are just that ie the piston and housing. Your inside brake pad that has worn unevenly could/is a sign that one of the caliper holders slider pins are stuck. With the caliper swung up out of the way the x2 17mm nut heads that that the 14mm caliper bolts that you just taken off, should push in and out and turn freely. If these are stuck then a new caliper won't cure your problem. Quote Link to comment Share on other sites More sharing options...

If i were fitting new calipers i'd be replacing them as well unless they are in good condition with no corrosion inside where the slider pins fit which is doubtful Edited January 7, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
pauldoug Posted January 7, 2014 Author Share Posted January 7, 2014 (edited) Thanks for your input guys, I decided to send the carriers away also as it was only an extra £10 to have them cleaned up. Im now stuck at the moment on how to clamp the hoses while I remove the calipers, I would like to let the fluid drain and do a full flush but have read a few stories on here about air in the system while all fluid is drained out, seems sensible to change the fluid while theres still the old fluid there as far I have read.

pauldoug Posted January 7, 2014 Author Share Posted January 7, 2014 im guessing this will do the trick? one for each side. http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_214147_langId_-1_categoryId_255216#tab3 Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted January 7, 2014 Share Posted January 7, 2014 If you got some spare 8mm silicone hose, you can cut a small piece, and wedge it in the banjo fitting, this is what I do on my Braided lines, as they can't be clamped. Or, what about a wad of blu tack squished in the banjo fitting? Quote Link to comment Share on other sites More sharing options...
pauldoug Posted January 7, 2014 Author Share Posted January 7, 2014 blue tack, that's the kind of diy thinking that im looking for :-) Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 7, 2014 Share Posted January 7, 2014 Smaller diameter bolt & nut with 2 washers, 2 x 1p coins either side and mole grips See if you can get a vacuum bleeder as they work very nicely and you can bleed the brakes on your own and no need to pump the peddle.

Mk4Gaz Posted January 7, 2014 Share Posted January 7, 2014 I tried the nut and bolt thing, but the damn fluid kept seeping through Quote Link to comment Share on other sites More sharing options...
pauldoug Posted January 7, 2014 Author Share Posted January 7, 2014 Just bought 2 of the laser hose clamps, just taken one out the pack and look like they will do the job nicely. Too dark tonight too go out and try, does anyone know what size of socket I need to take the bolt off at the end of the hose where it joins the caliper. Cant wait to get the calipers sent away.

I drive my car 300 miles a week back and forward to work so I don't need anything too performancey. Quote Link to comment Share on other sites More sharing options...
Dan_Q Posted January 7, 2014 Share Posted January 7, 2014 its not too dark mate, I'm off out to work on my brakes right now come on, you can do it! yep its a 14mm, slackened off mine on sat and re-nipped ready for removal tonight if all goes to plan. also when I did my research I came across the above threads mentioned- I have a vacuum kit on its way too, should make the job nice and easy to do alone Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 7, 2014 Share Posted January 7, 2014 I'd definitely be fitting braided lines at the same time Quote Link to comment Share on other sites More sharing options...
