Brake on 1988 indy 400 not grabbing well

6 posts in this topic

The brake on my 88 indy 400 is real mushy and only sort of grabs, it doesn't really work. You get it to stop the spinning track (when on lift and running) if you pull it all the way to bar, but i know it just is not working the way it should.

The pads look okay to us (non sled mechanics) it just seems like there is lots of space for it try to close. There is fluid in the reservoir. Any thoughts, or things to try first?

I have not ridden it yet since I got it, so I don't know how bad it is not working... smile

We did take the carbs off and clean and the main jets were gunked good, and it seems to start and idle great now. Hopefully it will stay that way! It does seem to want to idle UP after sitting - but like i said I haven't been able to ride it yet, and not letting it sit and idle for long periods of time.

Box, there might be some air in the line so you might have to bleed it out to get the "feel" back in the brakes. There's a bleeder on the caliper. On an older sled like that there may also be some crud or sediment in the lines as well. In that case you may need to disconnect the line from the caliper and drain all the fluid out of the line and the resevoir and flush it out and then replace it with some new stuff and then bleed it out real well and see if that helps. Sometimes those bleeders can get pretty corroded over time as well so you may end up replacing it in order for it to work properly. One last thing to check...the hub on the brake disk on those is splined so you may want to check and make sure that the splines on the hub are not stripped or check the jackshaft that the disk slides on to and make sure it's not stipped either. This isn't real common but it could happen. Good Luck

Just wanted to update you guys who had been helping me with my "Traded a canoe for the 88 indy 400" sled smile

I bled the brake, and it must have broke loose some air or gunk cause it just was not grabbing and not bleeding right, and hten all of a sudden it started grabbing perfect! I still need to bleed it again properly, but I got to put on about 10 miles this weekend.

Brake works great, starts great even in the -10 temps this morning up north. It even handles way better than I expected. But the suspension is a kidney buster on the bumpy parts as expected. The sled is so light and easy to drive and easy to pull over.

The only thing/question I have now is that there is something in the clutch assembly that is rattling and doesn't seem right. I think I mentioned it earlier, but it is a bushing or spacer or something = round with 4 half holes, alomst like it is supposed to catch on the spring or soemthing, and it just rattles on the shaft loose. When I hit throttle, it doesn't "ease" into movement it sort of "snaps" or clunks into engaging, not hoorible, but waaaaay noticle next to properly accelerating sleds. Maybe needs clutch rebuiling?... 4000 miles.

Otherwise it is running great, stopping great, starting great and it is a cool sled. I even had it up to 60 on the lake and it was fun! smile Going to put it through the ice fishing weekend next weekend, with a bunch of the guys coming up to chase pike and crappies, and this sled will be towing some shacks and fat guys wink

an 88 indy 400 that sounds like a liquid cooled sled, those suckers are quick, i had one that the odometer read 12000 miles on it and it showed every one but it ran like a top at all of 92mph, the suspension on those older sleds were a back buster but you didnt need a bachelors degree with 2 years of computer training to work on em like these newer ones, it sounds like it might be the rollers in the clutch might be getting flat, im no clutch expert.. wonder what NAMASD thinks

    • We are heading back up to Isle Royale for the 4th holiday weekend ,,, Hope to have another video when we get back 
    •   My Father-in-law (a master plumber) always used to say you only need to know 3 things to be a plumber:          sh*t doesn't run uphill         payday is on Friday         the boss is an ahole      
    • I've been getting them at Costco,  I've checked slyvee and sams but never see them.  Although one of the butcher's at slyvee says he can get them which might not be a bad idea since you can have some fat cut off before you pay per #. I picked one up a couple of weeks ago and it was about 2.80 a #, which isn't too bad yet considering bacon in the store can run quite a bit more than that.  You making bacon or doing pork belly burnt ends moon lake?
    • Excellent summer fishing.  Charters catching strong numbers.  Jig/minnow or jig/leech and bouncers with spinners with crawlers or minnows still producing walleyes. When the wind is right for pulling spinners, they have been lights out.  Walleyes being caught in varying depths, 7-31' of water.  Some shallow shorelines still producing. Pike mixed in all over the lake.    Walleyes in the Rainy River with a better morning/evening bite.  Trolling cranks or pulling spinners a good idea to cover more water. Smallmouth bass are out and about along shorelines and feeder streams. Sturgeon fishing opens again Saturday, July 1st.     Up at the NW Angle, water temps are in the low to mid 60’s. Wind blown shorelines are giving up walleyes via leeches or crankbaits along the weed line. Crawlers on a  gold and/or orange spinner are producing fish out of the mud between 22 - 26 feet. On the Canadian side, bottom bouncers and spinners have been filling the livewells outside of monument bay between 24-28 feet.  Jigging near Skeet and Kennedy Islands have produced nice sized walleye and numerous perch. Great smallmouth action in Tranquil channel and the mouth of Johnston passage. Muskie fishing picking up with high 40” class fish being caught with a few 50's from shallow bottom bays or adjacent to them.
    • Busy time of year out there so if u get canceled it is hard to rebook especially with the smaller operations. Bummer though as it can be a lot of fun if they are biting. 
    • I understand that you never really know when the Warriors are going to fall off or if they even will.  Hopefully the Wolves can make the playoffs and gain some experience, maybe teach the rest of the team how to play defense, so that in a few years we are knocking on the door and can lure in a top free agent to put us over the edge.  Its just an awful tough time to be a good team right now with the Warriors so clearly heads and shoulders above everyone else.
    • I couldn't have said it better myself pikestabber!  We have to go out there and do what we can now and not try to set up for "when the warriors are old" cuz the way the NBA is going who knows what players may join forces to set up the next "Warriors" squad.  Heck maybe the Wolves will be that next team !!  I just really love the addition of Butler and from the sounds of it we are not done yet and I am excited to see what will happen in free agency and if we could really land the likes of Kyle Lowry one of the other PG's that are hitting the FA market.  Nice to see the Wolves making moves!!
    • I would ask Getanet where to get some good ones!   Pork Belly Stinks Started by Getanet, May 1
