DiscoClax Posted September 9, 2007 Share Posted September 9, 2007 Hi all, I replaced the stock rear rotors with DBA slotted ones last weekend. New Bendix 4WD (AFM) pads went in at the same time. These are the same pads as I have always run (now on my third set) without any previous issues at all. Problem is that after the first two or three brake applications they start to squeal. Didn't happen initially, but as the pads started to bed in, this issue started to happen. Doesn't occur when dead cold, and improves if I've been motoring down the freeway for a while off the brakes and they cool right off. Gets progressively worse as the brakes warm up and starts happening at higher speeds. And I'm not talking " Oh, that's a bit annoying" type squeal. I'm talking "People in the next suburb looking out their windows with their fingers in their ears" type squeal. Driving me totally nuts. I change into low-range for carparks now so I can stay off the brakes as much as possible. It's really embarrassing and annoying in the extreme. I haven't had a chance to off-road on the new brakes yet, they've only done about 1,000kms of mainly highway work so far. Pistons are retracting properly, can't see anything obviously wrong with the brakes. Seems to be the LHS ones only, as well. I've tried putting anti-sieze compound on the edges of the backing plates and contact areas of the top retaining spring plates, and even chamfering the leading edge of the pads. No joy. No better. Still being deafened. I've avoided using an anti-squeal compound on the backs of the pads so far as that's always somewhat messy and coats the pistons and seal in gunk (and doesn't always work). Note that I don't have the pressed metal shims fitted (which appear in the EPC), but then I never did. Someone please help... My usual fixes haven't worked.
