box brakes

Over the past winter I got to 95% on a project that took waaaaaaaaaay to long, a full suspension refurb and rear caliper 38mm upgrade. This week and weekend upcoming nice weather should see the car come out of hibernation and get back on the road at least for a trip to the alignment shop...

This just popped up on YouTube. Not mine. Quite interesting to watch it all come apart. I reckon I might have sprung for a new seal kit, and have painted or clear-coated the caliper......but kudos to the guy for posting.....

So like many of us my OEM brake reservoir had cracks in the top. After looking at various ways to repair it I decided to do the dual clutch reservoir which has a lot to be desired but would work. Set it up but it developed a leak in one of the feeder tube, was going to replace it then I saw...

Managed to obtain a full set of Uno Turbo MKII brakes. Not sure what I’ll do with the rears but they surprisingly unexpectedly turned up with the fronts complete. I know the fronts are a direct fit for the X1/9 but my question is do the std X1/9 brake guards remain or do they need to be removed...

Certainly a subject that has been discussed and I wanted to go a step further. I have had the materials for some time, but things get in the way and the project gets backed up on the to do list. This issue at hand from my perspective is that a conventional brake booster with dual circuits...

Apparently an X1/9 that sits for even just a few months can have not just the brake master cylinder start to leak, but the clutch master can as well. Earlier today, I removed the pinch bolt, but have not had any luck in getting the shaft to slip right off. It seems rather determined not to...

About a year or so ago someone here mentioned using these little cone shaped copper washers in the threaded brake line (and clutch line) joints if they keep leaking after being tightened up. I got some for a leaking connection up a the brake master and they worked perfectly. Now I need one for...

I just finished replacing my front pads and rotors (a first!), and although it was not hard, it did have a surprising number of twists and turns. As usual, everyone on here is operating at a level far beyond me--which may help explain why I couldn't find a dumbed-down, step-by-step explainer on...

Mock up and test fit of the revised pedal box. Hand carved some lube channels into the SAE660 bronze bushing to aid in lube from the zerk fitting and move the lube inside the bushing to lube the clutch pedal pedal rod. The 1mm hole is near the zerk fitting the two 3mm holes are at the ends...

Since I have to drop the pedal bracket again to either mod my clutch pedal lever or install the Volvo clutch master, I'm considering replacing the stock brake master with something of a newer design/construction. Can't find any specific examples of this, I know we have had the discussion in...

As you may know I have been working on Bob Martin's Dallara doing an Abarth engine swap. As the project progresses, there are times when it appears that little is being accomplished. Many systems must be installed before the engine and transmission can be installed in the engine bay, that...

My newly acquired 81 X1/9 has a strange brake problem (this car had not been driven for a few years). The right rear brake will lock up and when this happens the brake pedal is rock hard with no travel. Once the car sits for 30 minutes and cools down, the brake is fine again -- sometimes...

I know we discussed this in another thread, however I can't find it :( I installed my BMW reservoir from Jeff Stitch today. Moved it over to the left & shortened the feed lines considerably. Secured with 13.8 Oetiker clamps. I moved the clutch res. outward for easier access until I figure out...

As we know the Fiat's brake line attachments use a odd sized nut fitting. Its a fine thread with Lucas tip for ISO/DIN bubble flares, plus a longer shank. The actual dimensions of the stock ones on my X measure: M10 (1.25) X 18mm overall length, for 3/16" line. I've found two sources that sell...

Seems like there are several brake threads going right now, so I'll jump in with something I have been considering. It's a given, based on what Bernice and other long-time Xers have posted, that replacing the stock 34mm bore rear calipers with 38mm rear calipers from the FIAT 125, 132, and the...

In another 'brakes' related discussion I mentioned something about the possible adaptation of front brakes from the "New 500" onto the "X". The new 500 has larger, vented rotors with larger calipers. Please, before this gets side-tracked...this discussion is NOT about the merits/faults of...

These started out as a pair of rear calipers from a 76' Lancia Scorpion. Quite icky directly from the Lancia. They were washed in an industrial hot water & soap washer then abrasive particle blast cleaned. This is what the brackets look like after being primed with Tempo zinc phosphate primer...

These Uno Turbo calipers have been ready for years to be installed. Finally decided to spend about 1.5 hours to get this done. Inside of the Uno Turbo caliper. Powder coated, new seals and all. UT calipers open, pads, M12x1.25, 20mm long, grade 12.9 cap screws, SAE hardened washers...

The 74' developed a dragging rear brake caliper not too long ago. This is usually caused by a stuck brake piston or a brake hose that is closed down over time that the hose no longer allows any fluid flow. Third is the brake master.. which happens less often. In this case, it turns out to...

The 74' needs to have it's brake master cylinder replaced after all these years. The current set of master cylinders appear to be OEM from when the exxe was made in 1974. It was not too long ago when the replaced brake master cylinder in the LeMons racer decided to act weird and inconsistent...
