rssh 59 Report post Posted December 23, 2007 What happens to the drum brakes when one forgets to remove handbrake apart for engine strain .Will the drum brake be changed if we don't get good braking later on. Quote Share this post Link to post Share on other sites
anjan_c2007 1 Report post Posted December 23, 2007 Oh God! that reminds me of my little Maruti 800 that when new was driven for about 5 kms with the handbrake engaged. The engine overheated but nowhere as compared to the old Jeeps (including a Mahindra pickup FC 160 ), Ambassadors and Fiats that I've faced with heated engines. The Mahindra's (this was the FC 160 - petrol driven, they also had a FC 260 D diesel option)engine was in the drivers cabin and as i was new I opened the radiator cap and steaming water splashed and hit the cardboard roof inner lining and burnt my hand. I was saved as a splash on the body or face would have been deadly. Compared to all this the Maruti 800 other than showing a heated meter on the dash felt nothing like these very very angry and heated up older automobiles. But very soon I had to replace the two rear drum brake pads as sometimes these would engage and disengage at their whims. Quote Share this post Link to post Share on other sites

If it were >100km I would get the linings checked. Quote Share this post Link to post Share on other sites
rssh 59 Report post Posted December 28, 2007 Well would wheel alignment be recommanded and brake pad changed if the brake makes squeeking noise. Quote Share this post Link to post Share on other sites
sgiitk 0 Report post Posted December 29, 2007 Alignment should not be disturbed. The brake squeal coule be due to the linings getting glazed, and this should clear in time. One common practice is also to lightly emery/sand the linings. This is not strictly recommended since any emery particles embedded in the linings can scratch the drums. However, if the linings are worn out then they have to be replaced. On a drum brake you can normally get a 'dekko' after just removing the wheels as there are small openings in the drum periphery.

rssh 59 Report post Posted December 31, 2007 Hey even after checking the brake pads they aren't worn but the braking power has become less what might be the reason. Quote Share this post Link to post Share on other sites
sgiitk 0 Report post Posted January 1, 2008 Glazing of the pads. See my previous post about mildly abrading the surface. I am not 100% sure whether in a few days the glaze will wear off, it should at least reduce. In any case over 70% of the braking comes from the front (discs) which are undisturbed since the handbrake does not apply on these. So may be you are imagining the effect to be worse than it actually is. Quote Share this post Link to post Share on other sites

sgiitk 0 Report post Posted January 2, 2008 In that case either changing or abrading the rear linings is the only option. Even though abrading is discouraged it is a fairly common practice (see that he uses a file or emery rather than sand paper). Before I knew better in once the mechanic lightly filed the linings before putting in newly lined shoes (that was when these were riveted on). Quote Share this post Link to post Share on other sites
