Indy R1 brakes binding
Hi all,
One of my SVA fails was excessive binding on the rear brakes.
My handbrake cable is fully loose, but there's still a bind (worse on one side than another) - anyone got any suggestions on what to check
next?
Cheers
Steve

disc or drum...?
If drums then most likely to be the auto adjuster mechanism for the handbrake. Failing that are the cylinders in good condition and able to retract
fully.

If it isn't the calipers then ------
Master cylinder piston is not coming 100% back against the circlip in the end of the bore -- ie mastercylindr pushrod is too long or mushroom head on
push rod iss too big or incorrrectly adjusted pedal stop.

Definately worth a shot - if that is the case it's a bit worrying that the bind is greater on one side that the other.
Probbly worth checking the intergrity of the copper pipes as well to make sure I've not defromed the pipes on one side.

If it's disks it is also worth lookiong at the following:
1) Winding in the caliper back in and refit the caliper, then pump the brakes to allow the self adjuster to work.
2) Then check that the foot break works and releases OK. (If not it would suggest either a fault with the master cylinder or the rear piston is
sticking)
Then if all OK, then pull the handbrake on, checking first that it grips, then release and check that it does not bind. (If 2) is OK but still binds
then it suggests that the caliper handbrake adjuster is at fault)
Cheers

check the rear pads, they have a small lump on the backing which should align with the piston cutout, if not engaged in each other this can cause the
brake to bind and drag

I totally forgot in my original post - I'm running sierra discs on the rear.
