Brakes
Someone plz remind me if drums are supposed to drag a little bit...I
mean a *little* bit. Went around on all four corners yesterday, drums were pretty dirty and pretty loose, I tweaked them a bit and changed out front rotors and pads, now I get a left pull on braking that matches pressure to the pedal. As an aside, my front left rotor was blued, so I will be doing all around brake bleeds tomorrow, and I will be crossing my fingers.... -- JPribe JEGP 98 TJ MSN:JEGP AOL:JEGP JPribe 'at' nc 'dot' rr ''dot com Disclaimer: A large chunk of the preceding was, in its entirety, written by the wisest of mules. http://www.----inggoogleit.com/ JEGP O|||||||O NC, USA |
Re: Brakes
JPribe,
Drum brakes should be adjusted with the wheel off the ground and to the point that you just her them dragging a little when you spin the wheel. After this first adjustment, step on the brake pedal a few times to make sure the shoes are centered inside the drum. Adjust the shoes again if the slight dragging sound has gone away. Repeat till you get the same sound before and after brake application. C. Ervin Someone plz remind me if drums are supposed to drag a little bit...I mean a *little* bit.

Sometimes a sticky caliper will act normal if you retract it fully with a C-clamp, and sometimes not. Check the right front caliper to ensure it's doing its job correctly too. John |

With new brake shoes, the rough surface should drag a bit on instillation. This wears off very quickly. If you adjust things so that no drag is felt at all, you will have a very low pedal and not much braking. Having owned 5 4 wheel drum brake cars in my lifetime, and several rear drum/front disc vehicles, I've been there, done that. On a relining job, most cars should be put together so that the drum is noticeably difficult to turn with the wheel off. One the brake shoes have worn a bit (doesn't take much, a day or so of ordinary driving), if you take things apart, they should be put together one "click" before they start to drag. By that time, the rough edges have worn off and the shoes have conformed to the drums. Just my experience. DAve |
