Car Forum / UK Car Forums / Car Maintenance (UK group) / October 2007escort brake question(s)
ok - when cold the off rear brake makes a grinding sound (but only for a few minutes a day) so today I had the drum off to have a look fully expecting to replace the shoes, the trailing shoe was worn more than the leading shoe and both shoes had a glazed look (I was expecting to find the friction material riveted to the shoe - and the rivets grinding on the drum - its been a while - 30 years since I changed brake shoes) .The near side shoes show the same uneven wear but not the glazed look, and doesnt grind. Picture of offside rear drum here http://www.niknkelly.myzen.co.uk/scortoffrear.jpg is it normal for the trailing shoe to be more worn than the leading shoe? Whats the minimum thickness before they need changing? There is no obvious leakage of hydraulic fliuid but could a little ooze out, cause the grinding and leave the shoe glazed? > ok - when cold the off rear brake makes a grinding sound (but only for a > few minutes a day) so today I had the drum off to have a look fully [quoted text clipped - 15 lines] > There is no obvious leakage of hydraulic fliuid but could a little ooze > out, cause the grinding and leave the shoe glazed? the shoes are different thickness to start with. pull back the rubber boot on the cylinder, it should be completely dry underneath, any leakage on either side means you should replace both sides, clean out the drums and de-glaze them. a millimetre or so at the thinnest point is as low as you should go, brake shoes are very cheap >> ok - when cold the off rear brake makes a grinding sound (but only for a >> few minutes a day) so today I had the drum off to have a look fully [quoted text clipped - 21 lines] > and de-glaze them. a millimetre or so at the thinnest point is as low as > you should go, brake shoes are very cheap cheers for that - the drums are fine its just the shoes on the off side look glazed > ok - when cold the off rear brake makes a grinding sound (but only for a > few minutes a day) so today I had the drum off to have a look fully [quoted text clipped - 10 lines] > > is it normal for the trailing shoe to be more worn than the leading shoe? The trailing shoes aren't worn. They make them thinner. > Whats the minimum thickness before they need changing? The linings usually fall of before they wear out! But at the very minimum, about a millimeter. Main thing with shoes is that the lining is still firmly attached to the shoe (ie. no signs of any cracks between lining+shoe -usually at the ends), and there's nothing it getting near to touching metal on metal. > There is no obvious leakage of hydraulic fliuid but could a little ooze > out, cause the grinding and leave the shoe glazed? It would be obvious if the cylinder was leaking, as the area around the cylinder would be damp/wet. Have you checked the handbrake cables are free, and that the lever on the shoe goes all the way back against the stop once the handbrake is released? >> ok - when cold the off rear brake makes a grinding sound (but only for a >> few minutes a day) so today I had the drum off to have a look fully [quoted text clipped - 30 lines] > shoe goes all the way back against the stop once the handbrake is > released? thanks - I think the last time I looked at brake shoes were for a hillman superminx - a little while ago, the handbrake cables both run ok but I didnt check whether the shoe released ok. The handbrake is on 6 clicks at the moment and holds fine.

The cylinder in the photo looks moist - could that be due to leaking fluid? Lift the cylinder dust cover and check under it for any fluid.

Ah! Looked like something that you'd appended to your call like "stroke P" or "stroke MM". I just couldn't figure what "brackets L" was ... Arfa |
