Caliper is new still does't back up could be bad abs modulator

this is brakes 101 topic
called basics.
binding means what, dragging brakes. ????? x4
got ABS not told???????
no year told , no country told
all 4 dragging , means MC is bad ! (and most easy to prove)
or the pedal that drives the MC is set wrong linkage adj.
the MC piston inside MC must 100% fully retracted for foot off pedal
pressure TO GO TO 0 zero PSI. zero bar.. zero Kpa
next up is ABS bad, the main modulator is bad. (rusted max inside)
to prove that is easy, brakes 101
we open the input port to ABS to MC and if drags ends, MC is bad,
if not the ABS is bad.
some cars world wide? have a brake balancing device, in the lines too.
I can not guess you country and know what is really there ever.
who long did car sit unused, 1day 1 month, 1year , 5 years?
if sate long
we open each caliper bleed screw and if this wheel still drags
that caliper is bad, for sure, (brakes 101 )covered in all books in print for 100 years, back to drums. same answer, (minus ABS)
emg, brakes is a whole other set of tests.

ABS ????????
crack the line to that brake, caliper
that means the fitting, not to break it.
loosen the fitting to that line, and find who is blocked.
my guess is you put in the MC and did not set the back side pedal
rod gap. per the FSm. spec?
did you use the FSM as a guide? or guess.?
1: new MC
2: new rear cyl./
3: old calipers.
so did the old calipers work before and how long was before. 1 day, 1 year?
if you loosen the rear hose fitting to the caliper that jams
and it release, the lock the the problem is up stream.
if not dont release the caliper is bad.
easy huh, just a turn of the wrench.
even bad calliper sliders can jam a rotor and that is the first thing
i check on calipers after leaks.
they must slide and float, if not they are dangerous.

if ABS , nows to time to say,
if ABS did you first read the FSM pages on how to bleed ABS on this suzuki, some cars need a special scan tool to get the ABS modulor
working right, (specials steps)
good luck there.

ive never seen a wagon R, we dont have them here.
so do post whats there.

Honda had two brake reservoirs one on the normal brake master cylinder the other on the ABS module. If abs fuse has no power the module has no power. that power comes from the main fuses in underhood fuse box. the abs system is supplement system to normal braking system loss of brake pedal is a air problem or drum brake adjustment problem or a loose wheel bearing pushing the caliper piston back into caliper requiring more fluid to get brake to work causing a low pedal.

possibly a faulty caliper

Check for loose wires to the ABS module and have the module checked. This could be a bad Caliper but it sounds like it is the ABS module malfunctioning.

You have a caliper sticking or a problem with your rear brakes. This could be the caliper, a bent Brake line, a bad Master Cylinder or a bad ABS Module.

Disk brakes are automatically self adjusting. If you have too much travel in the pedal, bleed the brakes. Let us know if you need the procedure.

bleed all connections in the system especially the four in the abs unit. good luck

Is your ABS light on? If so, you have a bad wheel speed sensor at the LF wheel. Or, you may have rust buildup on the teeth that the speed sensor measures. Pull off the axle, and check the toothed gear that resided in the spindle.

If not, you may havea sticking caliper piston, or inadequate lubrication on the caliper slides.

We have the same problem with our BMW. Dealer quoted close to $1500, with a one year parts warranty. Go to Module Masters at www.modulemasters.com.

They show detailed info on how to remove your unit, and will rebuild one for a 2001 XK8 for $150. The unit for our BMW is $300.

I have heard great comments about Module Masters. Well worth a shot!
