Hello everybody; My 1991 TC seemed to need brake work and my grandson and pal who took auto mechanics in high school said they could do the front brakes . I made copies of the brake chapter in the manual. They replaced pads, rotors, calipers, however they could not get the brakes to pump up, the brakes worked before now the pedal goes to the floor. They ran more than a gallon of fluid thru them. Other than following the instruction, is there some special way to fix this. Garages in Canton Ohio have been no help. thanks Tobruk

I'm gonna take a stab at that they put the left caliper on the right side and the right caliper on the left side. What happens with that is the bleeder screw is no longer at the top of the caliper and try, try, try as they will, brakes will never bleed the air out that way.

Also, did they follow the bleeing procedures JUST like the book outlines? The TC brakes can be tricky...

Hi,
Just to add to Alan's reply. To bleed these brakes you must follow procedure. not like any procedure that was taught in school. this is a completely different engineering system than normal hydrolic brake system. If you have a problem understanding please ask we will help.. Good Luck, Lou

Thanks for the replies, The guys followed all the procedures they had learned in auto school. but they did cross bleed the brake lines; I see now how they got into trouble if they had not replaced the calipers every thing might of been OK. LouZ thanks for the good luck wish and
TwinCamFan I'm going to check your sugestion first. I'll give a follow up to you when I've had a look. Tobruk

Tobruk, Because the bleed procedure is so different than normal, and can be confusing, Here is a quick procedure. TC brakes want to be flushed, by bleeding every 2 years.(only use DOT 3 or DOT 4 fluid never that silicone stuff) Pump brakes about 25 times to release & equalize pressure (TC Brake system holds about 2900 lbs pressure internally) Remove resiviour cap and fill. Remove rear wheels, Crack rear bleeders loose, and retighten. TURN ON KEY , When system motor stops,hold brake pedal down, bleed right rear wheel (with key on,Brake pedal depressed, and bleeder open, fluid will run. when clear and no bubbles shut off bleeder and tighten, do the same to the left side. Turn off key, Put on wheels, pump down pedal 25 times again, remove cap and fill brake resiviour.. Leave key off remove front wheels, loosen & retighten both bleeders pump brake pedal 3 times and hold down bleed right front wheel, do this 3 times should be sufficient. bleed left front, Put on wheels, Check fluid again. turn on key, wait until brake system pump stops, now check pedal TC have a self setting pedal according to your use and pressure you may have to drive it a little to get the optimum set from the system.. ~ But ~ do not drive it if for some reason you have no pedal.. Good Luck, Lou

Very good LouZ , I printed out your directions, tomorrow night I'll give it a try. Thanks Tobruk.

Hello; TwinCamFan,and LouZ I followed your instructions to the letter, Alan your stab at the problem was dead-on; after switching the calipers so the bleeder was UP then following Lou's directons to bleed the system I was able to drive the "Black beauty" home. Yes the feel of the pedal is strange after all I only drove the car one time (20 miles) since I bought it, the car has sat in the garage the last 19 months . If after driving it I like it, I'll keep it, if not I'll put it up for sale and thanks to both of you I can . Happy FOURTH of JULY, Canton is a busy city this time of year with the FOOTBALL HALL of FAME, I might try to drive it in the big parade. Thanks again TOBRUK.

I think I deserve a cookie

Good Call Alan, I'm just lucky enough that I never had that problem, & never thought of it... Lou

one more reason these cars are so special ,with help like that , no other mark has this kind of support , Alan go ahead and take 2 cookies

HI! I'll take some photos of the TC so you will see what you have saved from being a PART OUT CAR ---- TOBRUK Canton Ohio, ( tobruk710@sbcglobal.net )

"I think I deserve a cookie" says Alan.
Alan I think you should have an entire package of Orio Double Stuff Cookies as a reward for this one.

In your line of work Alan, have you ever come across someone installing a hinged part backwards, say an arm or a leg that swings the wrong way?

"my grandson and pal who took auto mechanics in high school said they could do the front brakes."

This says a lot for high school shop class, doesn't it?
