Just in case anyone is interested in the difference, fitting them with shims at the weekend

forgot to say that the blue ones are the endless ones

Nice one Karl 8) Be interesting to hear how they work out m8 - they look smaller than the stock ones and with less pad material perhaps? Keep us informed how it goes :)

Cheers,
Mark

Hmmm...possible problem maybe :(

I have done the front pads this morning, all went well; the only 'unusual thing' that happened was whilst fitting the o/s pads into the torque plate the disk came loose when I nudged it with my arm. I thought "that didn't happen when I did the job last, but then perhaps I didn't nudge it with my arm last time".

I thought little of it; with the caliper assembly detatched there is nothing holding the disk on is there :?: Continued the job and had a hard drive home to start bedding the pads in :twisted:

I stopped at a local garage for some vodka and red bull, and thought I would run my finger down the disk face to see how the surface felt. OUCH...how hot :shock: Now I know disks normally get hot, and was expecting to feel a little heat, but OMG my finger is now a charred and crispy stump :cry:

Did a more detailed examination, which meant spitting on the disk....sizzle sizzle instant evaporation. Touched the alloy wheel and it was easily holdable, but it was hotter than I expected. The n/s disk was nowhere near as hot as the o/s (but still hot) and the alloy was only slightly warm to the touch.

I took the handbrake off and the car rolled easily without noise with a gentle push...I was thinking perhaps the pad was in constant contact with the disk?

What do you boys and girls think, am I being overcautious, or is there a problem? I will go for a drive later and try not to use the brakes and then feel the disk to see if it is hot, and will take it all apart tomorrow (I really cannot be bothered today) just to check.

Might the new pads generate more heat?

Should the disk be loose when the caliper is removed?

If you have read this far, thanks for staying with me, and if you have a response even better :)

Cheers (with a pint of vodka redbull in my hand)

the disc is free to move once the caliper is removed. its only held in position by the wheel nuts and the caliper biting it :)

it sounds like you have a sticking caliper...but it is a strange coincidence for it to have occured at the same time you changed pads. whip the caliper off, strip and rebuild it. look for any rust or grit etc mashed in the side of the piston. you can buy a caliper refurb kit from toyota for a reasonable amount

thanks for the advice andycaca

I was hoping to spend almost nothing on these brakes, and just replace them when the discs have worn out with some four/six pots and bigger discs...but as always it is never as simple as that is it :roll:

Karl - you might find that the calliper is sticky or does not slide?

Cleaning up and regreasing the slide might be a quick cheap fix?

Kris...did this earlier

It took some serious persuasion to even move the torque plate up and down, never mind side to side along the slide rod?; total lack of lubrication was the problem I think. I copper greased the slide rod and rebuilt the caliper.

Hammered it home stomping on the brakes loads, and the temperatures at the end were far more acceptable

I take it this job is what you were referring to?

Thanks for the help
Karl

Karl - yep just the ticket, should improve the brakes a fair bit.

This is gonna sound bad but you might have to do the job again v soon as copper grease shouldn't be used on anything but the rear of the pads imho.

I think this reacts with the rubber and causes it to swell and go "weird" resulting in a requirement for new seals :(

Must say again, that camera of yours take some good pictures! :D

Cheers Kris, it is just a small Pentax Optio S5i...I just press the button and it does the rest :wink:

That's interesting about the copper grease...at least it is only a 10 minute job and an easy one at that if I need to refresh the rubber...I will keep an eye on it

Right...done plenty of miles now, making the pads work hard and I reckon they are pretty well bedded in. The brakes are FAR superior than they were before the endless pads went in...they were MrT standard prior to the swap.

The bite feels instant in comparison and more powerful...I can't really tell you about their fade resistance as the 165 standard brakes are so poor it is hard to decide if it is the pads that are 'failing' or the whole brake system being overwhelmed.

IMO...these endless pads are superior to MrT's :) I would recommend them.

I have had to remove the endless pads...they may bite harder than the mrT standard ones but they are noisy and squealy beyond belief :shock:

It got to the point recently where I would feel guilty applying the brakes in urban areas. No noise when braking hard, but for normal daily driving in traffic I was finding driving the car tiresome.

I can handle exhaust rumble, engine and induction roar, tire and wind noise but not screechy brakes

Did they always squeak or did it get worse gradually?

For the first couple of days they were ok, and then they got worse and worse and just stayed noisy.

I fitted them at the same time as I fitted anti squeal shims, so kept playing around with different arrangements/rebuilding of calipers/bucketloads of copper grease lol etc not feeling too sure of what the problem was, pads/shims/sticky calipers?

I then did a straight swap to mrT standards and hey presto...no squealing!

I kept them on for a good month of hardish driving hoping they would 'settle in', and tried changing the shims/removing the shims, yet the noise remained :x

They will be up on ebay soon :lol:
